I've had her for almost 3 years. Suddenly last Sunday she decided to roost in the crabapple tree which hangs over the run. The first night she did this, I went out & climbed the ladder and grabbed her, boy did she SCREAM & SCREAM! After I got her in the coop, I shined a flashlight in there so she could see where she was and finally calmed down. I let them out for little while on Monday afternoon, and went to check on them & she flew up into the tree again, only higher this time so I couldn't reach her. Why would a bird suddenly decide to do this?? I have them in lock up now to try to break this habit. They were out for a little while yesterday, when I saw her enter the run I closed her up so she wouldn't do the tree thing. She kept trying to fly up to the overhanging branches while she was in the run. Her silly self kept crashing into the wire of the run until she gave up and sauntered into the coop like normal. I'm thinking something frightened her. The others don't act this way. Anyone have any other advice?
