I came home from a bike ride 2 days ago and it was getting dark. I went out to shut the coop and found only 2 out of my 12 chickens on the roost. Found them, all but 1, roosting all over the yard! Took a while but hubby and I got them all inside. Last night I made sure to go outside around the time they usually go back in and they were starting to roost in the same spots again! We FINALLY, after about an hour of chicken herding, got them all back inside the coop. Any ideas what is going on??? I've had 5 of them for about 2 years and they have ALWAYS gone back inside. I got 4 more last year and they have also always gone back in. I have 3 new ones that are about 4 months old but they have also always gone back in. If I don't let them out for a few days will they forget about trying to stay outside?
