I recently acquired one black sex-link hen and one red sex-link hen. I'm trying to get them acclimated to the sole survivor of my original flock, which is a 7 month old Easter Egger. The new girls seem like they might be a little older, and since there are two of them, they're picking on the EE some. They've got it down to an acceptable level when free-ranging, but I'm reluctant to put them all in the coop together at night. So, the new girls have been sleeping on a roost in the fully enclosed run. But, the last few nights the red one has flown up into a cedar tree that is right beside the coop, instead of going into the run. I chase her out of the tree and herd her into the pen. I wouldn't care if she chose to roost in the tree, if it's safe, but I have my doubts. Raccoons will just climb up and take her out while she is sleeping, won't they? They don't seem to startle very easily when they're asleep. Also, I'm just about to the point where I would like to try putting them all in the coop at night, where they're both safe and protected from the weather. So, two questions, or rather one affirmation and one question. Am I right that roosting in the open, even if it is high up in a tree is not safe? And, what's the best way to bring the new girls into the coop, with the least amount of drama?
