I have a hen that has decided to roost in a tree next to the coop. It all started when we got home after dark one evening and their coop door had gotten closed by the wind. I was able to get everyone else in except her, she was too high. The following evening she did it again even though the door was open. I was able to get her this time.The next evening I herded everyone in early to make sure I got her before she got in the tree. I kept everyone lock up for the next several days hoping this would reacquaint her to where she should sleep. Nope, she went back to the tree, I was able to get her down and in the coop. I did the lock down again but it's not working with her. I have to make sure I herd everyone in before dusk. There is nothing wrong with the coop everyone else goes in. Her and a roo were the first chickens I got and they are inseparable except for this. I am getting so aggravated with this. We have a very large owl around our place and I'm afraid he will get her. I know this might sound crazy but I don't think my Roo would be the same if he lost her. they seem to be a couple. Is there any way to stop her from doing this? Thanks in advance for any advice you can give.
