Been wonderin' and waitin'. It's been 21 and a half weeks of growing our 9 hens (and three roos). Put two ceramic eggs in the nest boxes about two weeks ago. Noticed the three leghorns' combs getting big and red during that time. This afternoon I go down to let them out to free range, I open the lid and there's a white egg laying right next to one of the fake ones. Yippee!
