They will not roost in the coop. They want to roost outside. They are 7mos old and she is laying. I have 6 hens and my Brahma rooster. My coop is 4X8X8. There are 3 nesting boxes and a roost that is 6ft tall. It is about 3ft wide made like a ladder. Why want they go in the coop? Should I run them in everynight anyway. It is starting to get cold at night and Im not sure what to do with them. T he other hens go right in. Now I just got the other 5 hens they are all less than a yr old and raised by someone else. Im thinking my 2 were raised in a smaller coop and run and it was very hot here in GA. Maybe they are not used to the run?
