Hi- This is our first time with chickens... So I have quesions about the egglaying.. One of my chickens laid an egg today. I don't know what time it was. When I saw it, it was in the middle of the coop floor. Could she have laid it while she was on the roost? The shell was cracked, but wasn't opened (like, the yolk wasn't exposed). When will that egg go bad? All we did was put it in a bowl. How do I get them to lay in the nesting box? I need a lot of information on the whole egglaying thing. Thanks!
