My chickens are around 19 weeks. We had some trouble getting them to roost because they kept sleeping on the floor of the coop, especially the nesting boxes. So we blocked the nesting boxes off for several weeks, and eventually they all figured the roost out. Sometimes one or two would be down because it was a little crowded, but we have been culling the roosters so there is more room now. So...in anticipation of eggs we opened the nesting boxes back up and....again they are back in there! Why don't they like the roosts? The roost are higher than the boxes. We are using rounded branches, but I just read maybe 2x4 would be better? We tried one once to no success, but that was back in the early days when they really didn't want to roost. Any ideas? I was thinking since they probably wouldn't lay at night, I could block the nest boxes up at night again and then open them, but I wondering if there is another reason why they seem to sleep there. Oh, and they all like to cram in together, which is really funny! Nobody I know has had this problem, so if you have any advice I'd appreciate it!
