Our silkies were born at the end of March, and yesterday I noticed one in the nest box in the AM. Told my husband that I think we may get eggs soon, though I thought that was just wishful thinking....but this am...a perfect egg! Now, a few questions....it's not being sat on currently....we have one rooster to 5 hens (I think)...should I expect a few more and then they'll be sat on, or do the hens not really understand to do that at their young age? Is it likely to be fertile? I see the rooster doing his manly thing with the ladies, and I'm hoping to get a new little bunch of chicks before I have to get rid of the rooster (we're in the city, he's not allowed, and he definitely makes his presence known). How long should I let the egg sit before I'll know if one of the chickens will sit on it, and if it doesn't get sat upon, how long would it still be edible?
