I agree with everyone else. 30cm per chicken is not enough. They need minimum 1.2 meters each. That should really help with attacking eachother. Also as others said they need some roosts.
That looks like some bad bumblefoot, their bedding is getting too wet and not drying out, a lot of chickens in one room will do that. Is that the only one with it? What bedding are you using?
