I have one chicken that gets out of the pen every day. She actually jumps/flies the coop daily several times a day. I think she must not like the other chickens since she doesn't seem to want to be around them much. She prefers to spend her time in the goat pen. I knew she had to be laying her eggs somewhere and decided to start looking. Found a nest of 11 under the goat bench in their stall in the barn. I have to literally get on my hands and knees to be able to reach the nesting area.
I think I'll name the chicken Freedom. I can just picture her yelling that as she hops the fence every day. FREEDOM!!
