I posted this last week but I'm still having trouble with them. They have ALWAYS gone in at night, so I'm really not sure what is going on. I haven't seen anything different in the coop, no rats or snakes or anything. The weather is really not that hot right now because of all the rain, so I don't think that is it either. The only thing that is different is I have 3, 16 week old chicks that recently integrated with the group. There is not really any fighting going on, even though they steer clear of the adults. They had been going in with no problems until last week. I left them closed in the coop/run area for 5 days to see if they would "forget" about not going in, but I had trouble with them again trying to get all back inside. I can pretty much herd the adults in, but the little ones won't go. Should I separate them again and see if that fixes the problem? I really don't know what to do because they so love to free range and since all of this started happening their egg production is way down. They have plenty of food in the feeders, but maybe they are not getting enough since they are used to free ranging in the afternoons. HELP!
