I don't have a very large coop. It is about 12 sq ft. I have 9 small bantams (under six months, some only 3-4 months old). All of them are hens and relatively docile at that. I have not yet designed an automatic door, being extremely low on funds. I'd like to visit my parents for a few days and worry that without being able to close the door, something will eat them all in the few nights I'm away. Would it be possible to keep them in the coop for those few days and nights? It has good ventilation and lots of space to roost, nice nesting boxes. I don't want to get back and see that they have pecked each other to death, but I have no one to open and close it for them.
