I've read where you can feel around the vent of a hen and feel an egg inside but I've also read that you cant.. What's y'alls opinions? My hens are being bad and laying eggs all over the yard. I can't find most of them. I have them in the coop this morning until all eggs are laid. I have 5 so far. I want to let the chickens out who have laid already but I don't know which ones have and which ones haven't .
