Major behavior issues within flock (lots of fighting)

I agree wholeheartedly.They need a proper coop with roosting bars instead of shelves.It would help to lay horse pellet's down on the floor. It absorbs moisture and cuts down on odors too. I didn't see any ventilation which is very important. When keeping multiple flocks in the same coop it helps to have separate roosting bars

Having an automatic chicken door is a big help. Set it to open at a certain time, and you won't need to run outside to let them out of the shed.
