Mine are 9 weeks now and have been going in on their own! I There is hope!!! Don't give up

!! I did the whole pick one up and stuff her into the coop only to have her come right back out while I'm trying to catch the second one and I did it every night for 2 weeks. One night I just thought- fine guys, if you want to sleep outside and be exposed to all the elements who am I to judge?? I don't want to be a part of this- you guys go figure this sht out. My husband fully supported my decision because he thought I was being a helicopter parent trying too hard.
Then 20 mins later.... they all went in on their own.... Like last post said, it would need to be kinda dark for the chicks to want to go inside.
