New to this; raised from chicks, I have 14 hens at 17 weeks old (haven't seen any eggs yet). This last week, every night they go into the coop they fight for one corner. They laid all over each other in one corner, pushing and squawking and taking flight. The rest of the coop is free and plenty of perch space. Is this normal? I've leery I'll come out in the morning and one will be dead.
