Electrical and predator proofing
I have a shed about 30' away from the coop that is fed by a 50 amp breaker from the house. I took off of that panel a 20 amp circuit that is partially in conduit, partially just buried underground wire to the coop. Everything inside the coop is in conduit and has covers designed for wet locations. All I have is a GFCI outlet that also serves as protection for the light circuit. The wire is actually underground wire that is inside conduit because it was cheaper than the standard romex at the time of purchase.
Predator proofing was pretty standard fare. 1/2" galvanized hardware cloth adhered with 1/2" staples put on with an air stapler. I ended up having enough OSB to put in a loft with an almost 8x4 floor, with the rest of it covered with hardware cloth. I used blocks of wood to seal the space in between the ceiling joists for the eaves. The loft door is made out of pallet wood and has hardware cloth attached to it. It allows plenty of ventilation as well.
