I have 5 hens and 1 rooster that are about 10 weeks old and are all lying in one corner of their coop. I have built them a roost about a foot off the ground its a 2x3 on its side. Every time I try and put them on the roost they just jump off and go back to the corner. I have even put obstacles in the corner and they still will try to get to that one corner. Any suggestions would be helpful.
