Our chickens are 19 weeks old give or take. We have 4. We went away for a few days and came home and looked and there was an egg in the nesting box. Our local farmer neighbor was taking care of them while we were gone so we thought he put an egg in there to play a trick on us. We went to his market this morning and he said no, he didn't. So I just went out back again and there was another egg. 2 eggs in 2 days. I know its just 1 chicken laying so the other 3 should be starting soon. At least I think it's just from one.
