We have 4 young chickens that up until this point have loved their coop. After they've been in the yard I could open the door and they'd gladly run in to eat. We had pine shavings and dried leaves for litter. This weekend we cleaned out the coop and litter because we had some rain and it got a bit wet as the roof isn't finished yet. The chickens were out in the yard while my husband was cleaning it out. He scraped the boards down and blew it out with the leaf blower-basically made a lot of noise and commotion in there. He then put down fresh pine shavings but no dry leaves. Well, they hens are refusing to go into the coop now. They needed to be wrangled and placed in one by one. Once in, they struggled to get out. It's as though they're scared to be in there. Yesterday was bad, today was terrible. They were flying onto the roof of the coop to avoid going inside. I was even throwing their favorite treats down onto the floor of the coop. What has happened? Could it be the litter? Or is it that he made such a raquet in there that they're scared? Should I keep them in the coop for a few days to fall back in love with their home? Any advice is welcome!
