Actually, I stupidly let her nest in an outside nesting box. She refused to brood anywhere else, so we gave in and let her stay where she wanted to be. Thought it was secure, but the skunk actually tore the latch off the front of the nesting box. It got in with her and was trapped by the door (hinged at the top). It bit her repeatedly and possibly broke her neck in the scuffle. I hate learning lessons at the expense of a life (numerous lives, as it also ate all her eggs).
All of our other broodys are secured in raised coops and the ramps are taken down at night. Small comfort at this point, but I am dedicated to learning ho to care for chickens in this predator laden environment.
