Over a month ago we installed an automatic door which I hesitated to get, fearing that a chicken or two would get left out in the run. Our run is 100% predator proof with 1/4" hardware cloth from top to bottom so I'm not worried about anything happening to them, I just prefer they sleep in the coop out of the cold and rain, at least during the winter. At first it was great and all chickens were going in on time but for the last two nights they've stayed out in the run and I've had to put them in the coop one at a time. The only thing I can think of is a couple weeks ago we put a roost out in the run thinking that might be nice for them during the day. Well this is where they've been the last two nights, ugh. Something else I should mention is we're using lights this winter in hopes of keeping egg production thru the shorter days. Our girls are only 19 weeks so we don't have eggs yet but hope to soon. I have the lights going on at 4am and off at 6pm. The door was also closing at 6pm also which wasn't an issue at first because they were going in the coop around 5pm'ish. Just in case, I changed the lights to shut off at 5:45pm for tonight but that didn't work. Probably because it's too dark. Any suggestion?
