I have 4 hens that I usually have to herd them into the coop at night. My dad came to visit who has chickens says he has no Idea why they don't go in on their own all the time. One thought was that I am inconsistent on the times I close them up. Sometimes 5 sometimes 7pm, and sometimes as late as 9pm depending on my work schedule. I think they like it in there are they are always on the roosts and I also keep food and water inside as well. Any tips on how I can get them to go in on their own?
