I think I've nurtured a bad habit in my chickens. Temps here are now below freezing every night but for some reason my chickens won't go into their coop at night. They huddle together under the coop in the run and will stay there all night. But if I go into the run to check on them, they all head up the ramp and into the coop. I have NO IDEA what is wrong! No mites in the coop (I use diacatameous earth with their bedding). Lots of space. Food. Treats. Water. Light. A little dust bath. They wander in and out during the day no problem but won't go up to bed unless I'm there to "tuck them in". How do I break that habit?! In the summer, when it was hot, they went to bed on their own, but when fall came they stopped. Anyone else have this problem/a solution? I'm worried they're going to freeze. Thanks!
