I put some banking around my coop and the pop doors on the south side to help insulate and keep the weather out about a month ago. Two days ago, one of my 3 month old cockerels went missing. I just found him wedged behind the bales. He must have suffocated or died from exposure. He is a pretty good sized bird, I just never imagined birds this age could get stuck behind the hay. I will have to make some adjustments. I am so sad. Just wanted to warn folks.
