Wow, that stinks! Tonight was the first night that, when I went to go put them in the henhouse, they had already gone in! We were later getting home than they usually are put to bed, though (I 'tuck them in' around 8 usually, tonight it was 9:30 when I locked the doors) Since they will be 5wks tomorrow, I've been really vigilant about going out to herd them in through the door (gotten to the point that when they see me at sunset they automatically head in). Sadly, last night the wind had blown their little door shut. When they saw me coming they ran to the coop door I enter by, chirping and peeping to tell me there was a problem! I opened their door up, and they filed in single file.. all but one. I called to her, and she headed in, too.
Since my group are still fairly young, if we have a 60-65 degree day, cool and damp, I don't let them out to play and leave them cooped up <sorry for the pun!> in the henhouse all day. They hate it, and will head for the people door when I go to check on them, but maybe that's why they KNOW they sleep there?
I do still have their light on out there, but they still settle down for sleeping.
I agree, maybe (if your weather is not too hot) leave them locked in the house for a few days so they get completely used to it, then let them out and herd them in at sunset? I don't carry my group in, only did the very first night, because I WANT them to realize that they need to go in (not wait for me to put them in). Kind of like human children, I figured if they had to do it on their own they'd learn faster. And so far so good.
Anyway, good luck to you! I can't imagine having to chase them around in near darkness!
