I Have two EE's that are about 8 Months old, they went into the coop every night all summer , then in Sept 1 of them started to Roost in the tree next to the coop, Then another followed it and then one of my SLW followed it. Every night I would have to chase them out of the tree ( SLW only did it once or twice ) and into the coop. I then locked them all in for a few weeks and tried it again still the two EE's were in the tree, I then locked them in for over a month and tried to let them out last night and the same thing in the tree. What to do? My twenty other Chickens and Guineas all return to teh coop.
