Sorry, I meant the run is 80 square feet and I woud say the coop is about 20-30 square feet. We feed them layer pellet feed. We give them 2-3 small cups of cracked corn on some nights depending on the temp. The one getting pecked is a Rode Island Red. I have 6, two are Rode Island Reds, two are Buff orpingtons, and the other two are Plymoth Barred Rocks. I will try to get better pic, but it has very few feathers and has a raw spot that looks like it was once bleeding. Any ideas would very well be appriciated!! Thanks!
