We came home tonight to find one of our Americauna chicks dead. They are 7 weeks old and I was just about to put them outside in their new coop. She was face down and all the other chickens were just walking all over her like she wasn't even there. Did I do it, not getting their coop finished by the time they were 6 weeks old? They were in a bit of a crowded space ... ugh, so sad. The rest seem fine though. Is there anything I should look for on the dead chick and/or on the others? Thanks!
