Collecting hens. Advice please.

remember to only clip one wing and then after they moult clip the opposite wing if you still feel a need to do so.

I think she flew because they thought bed was the top of the coop. They haven't done it again so I'm hopeful  that I won't have to clip them. I knew about only doing one wing but not about doing the other one after the moult, so thankyou for that Joyful.
They don't seem to want to mooch about on the grass very much. They sit under the coop most of the time. I thought that they'd enjoy the relative freedom. No sign of foxes digging yet so the electric fence seems to be doing  it's job.
