Help. My chickens decided about 2 weeks ago that they didn't want to go into their coop at night they were 16 weeks old at the time. Nothing has changed in thier enviornment. It started with me going out in my backyard to lock them up. I must say I went out at bit later then normal. It was completely dark. And they where huddled together on my bbq. So since then I have either been putting them in there by hand or coaxing them in with scratch. As of two days ago it got better but I have to stand next to the coop for them to go in otherwise they will go straight to the bbq. I inspected thier coop and didn't find anything out of order. And there is plenty of room for them. Btw, I have 3 barred rocks. And indication why they could be doing this and how it could be fixed. Because before this they used to go ihan on thier own with no coxing. And I never did it before 2 weeks ago.
