They will eat just about anything! There are commercial poultry foods available at local feed stores, or you can make your own mix. People feed chickens corn, oats, wheat, rye, soy, fresh greens from the garden (weeds as well), table scraps (they love spaghetti!), worms and other bugs. The local grocery stores and markets often have vegetable scraps available. Variety is the key to good health, just like us! See similar questions...

Not really. They are wild animals, and any wild animal should be treated with caution and respect, but the average armadillo is not a dangerous creature. They are capable of harming people with their strong claws if they are handled incorrectly, but in most cases they will run away when they feel that they are in danger. Most people who have had encounters with the animals have reported that the armadillo pretty much ignored them unless they did anything overtly threatening. See similar questions...

What you are seeing is Blossom End Rot, the result of a calcium deficiency in the plant during fruit production. You can solve this problem by keeping the plants evenly and sufficiently watered in dry weather. Plants with fruit require around an inch of water a week. Also try to water the plants at the base. A periodic soil test early in the season will tell you if you should add lime, which will also make calcium more available to the tomatoes. See similar questions...

This is also due to an uneven watering schedule. Try to keep the soil from drying out by watering regularly (be sure to water in the morning). A good idea would be to give plants one deep watering per week for most soil types; two waterings for sandy soils. You should also mulch the plants to help retain moisture. When choosing seeds or starter plants look for varieties that are labeled as crack resistant. See similar questions...

The current orientation is nothing more than a historical accident. The first map with chromosome numbers was published by Hawthorne and Mortimer (Genetics (1960) 45: 1085-1110). There were earlier maps by Lindgren and others but they did not name the chromosomes. It is clear from the first map the chromosomes were oriented with the long arm to the right of the centromere and this orientation has not changed. Since that 1960 paper, chromosomes I through X have been in the same orientation. See similar questions...

That will depend on the caretaker. Just like any other pet or animal, they need care--cleaning out the dirty bedding in the coop, keeping it dry and having a clean/dry area of sand or dirt for the birds to take dust bathes in. These practices will all help to keep your birds happy, healthy and odor free. See similar questions...

The key to safe chickens is a sturdy, impenetrable coop. Raccoons should be more of a concern, they are such clever, determined critters. .Make sure the structure is secure (enclosed top, fencing buried below ground under the sides, secure latches on doors or other entryways), keep all birds locked in at night, letting them out into the run or "tractor" only during the day.

Most growers market direct to grocery stores and supermarkets in their own area, usually within a 25-mile radius of their greenhouse. Local grocery stores are generally the best markets because they place value on excellent quality and good service. In addition, they like to purchase products that come from local sources.

No. And that goes for any food. It does not matter how anything is prepared if it is derived from the same basic food stuff. See similar questions...

See the online poster, Human Genome Landmarks: Selected Traits and Disorders Mapped to Chromosomes. This poster provides chromosome-by-chromosome maps of some of the genes, traits, and disorders that have been linked to each chromosome. These maps were generated using the Online Mendelian Inheritance in Man database. The Genome Database (GDB) and the Human Genome Map Viewer available through the National Center for Biotechnology (NCBI) are other resources that you can use to browse the genome.

The discovery of the chromosome was descriptive from the beginning and inseparably interwoven with the discoveries of the cell and the nucleus. All findings became possible only after Leeuwenhoek?s invention of the microscope in 1674. In 1831 Robert Brown described the 'areola' in orchids being constantly detectable in all cells. He called this areola'the nucleus of the cel'.1838 M. J. See similar questions...

ldquo;Full Aneuploidy Panel” tests for chromosomes 13, 15, 16, 18, 21, 22, X and Y because these are the chromosomes that are most commonly abnormal. A normal cell should show 2 FISH signals (or lights) for each of the numbered chromosomes, and either 2 X signals for a female or 1 X and 1 Y signal for a male. There are only five different colors that can be used, so most tests are done in two parts. See similar questions...

Wild armadillos have been known to be infected with the bacterium that causes leprosy (Hansen's disease). The only cases of transmission from armadillos to humans have occurred in rare incidents in which people ate undercooked armadillo meat. See similar questions...

Yes. In many areas of Central and South America, armadillo meat is often used as part of an average diet. I have heard that some peoples of South America keep small varieties of armadillos as edible housepets. During the Depression, armadillos were often eaten by hungry people. They were called "Hoover hogs" by people angry with then-President Herbert Hoover's broken promise of a chicken in every pot. The meat is said to taste like fine-grained, high-quality pork.

Three reasons. First, armadillos will eat carrion, which in the US is often roadkill. Animals that eat roadkill often become roadkill themselves, because they are on the road more often than other animals are. Second, armadillos are nocturnal. It is hard to see animals by the side of the road at night, so it is harder for motorists to avoid hitting them. Third, armadillos jump up in the air when they feel threatened.

I'm not exactly sure about this one. The best information I have about the lifespan suggests up to 14 years in captivity. Extrapolating from other similar-sized mammals, I would guess that the average lifespan in the wild would be between five to seven years. See similar questions...

Farmers have blamed armadillos for ruining melon crops, among other things. Raccoons are probably the biggest culprits. Armadillos seem to suffer from the same problem that hyenas do – their bad reputation appears to be a result of being in the wrong place at the wrong time. When farmers come out in the mornings, the slow-moving armadillos are seen taking advantage of the raccoon's leftovers, so they get the blame for ruining the crop. See similar questions...

When buying and handling live chickens, try not to touch them or their droppings. Do not blow at their bottoms. Egg shells may have been contaminated with bird faeces. Wash the outside of eggs and wipe them dry before putting into the refrigerator for storage. Observe food hygiene when cooking chickens and eggs. Always wash your hands thoroughly with liquid soap and water after handling chickens and eggs. See similar questions...
