The view of several well informed and experienced breeders that I know feel that the minimum time is four to five days. Some consider the minimum time to be 48 hours, others 36 hours. I have never sought to determine this fact. See similar questions...

It is suggested in the book Taking Charge of Your Fertility by Toni Weschler, but it probably is not a good idea ? most eggs in the United States contain salmonella and you risk the possibility of becoming infected. It would be better to use something else as a lubricant. The rest of the book is great, but this is one piece of advice that may be safer to avoid. See similar questions...

If the hen lays irregularly by skipping a day or two or more in the laying of the whole clutch, it means the rhythm of nature is not functioning properly. This is common in early season breeding, or if she is not in top condition for breeding. It is unwise to breed this hen. She might set on her eggs for a few days and then desert. If she does desert, the eggs most likely are infertile. Even if the eggs are fertile, the chances of this hen being a good feeder is poor. See similar questions...

Jack and jennet foals should be separated at weaning (between 5-7 months old). Most young jacks can become fertile after age 12 months, but we know of confirmed cases of several 9-month old and one 6 month-old jacks settling jennets. It has also been noted that a 12 month old jennet, while rare, can become pregnant. Think teen-age moms. Jennets should ideally not be bred until over the age of 36 months (3 years).

The Egg differs from the Twiddler in a subtle but significant way: The egg was designed to address the problem of autonomous usage; of capturing ideas and accessing information when the desktop computer was not nearby. The Twiddler, by contrast, only identified three-handed operation as a problem, the resulting solution is designed for use when you're tethered to a workstation, just like the keyboard.

You know, we're a little cloudy on that, too. Some say its because the egg shape provides the ultimate package for this unique liquid solid. Others believed Peter Hodgson, the marketing mastermind behind Silly Putty did his most creative thinking over scrambled eggs and bacon.

It will last for thousands of performances! If it gets dirty, you just wash it with water and mild soap (be careful not to get water inside the egg, it takes a long time to dry...). When it's clean it gets a little sticky. To prevent this, you add corn starch on the outside and the inside. Corn starch is used for making sauces and for other cooking purposes, and your mother will tell you where you can buy it. It costs almost nothing. See similar questions...
