I wouldnt worry too much m8, Ive had this problem b4 too, I saw other people with lots of cocks running round with each other so thought I would let all mine out 1 day, together. They went mad and while I wasnt there they tore each other up. I didnt think my sussex cock would survive, his whole head was covered inn dry blood, his eye was stuck shut, but over less than a week, he fully recovered. He fought a shamo x sussex, and lost..... Got rid of the shamo now, didnt realise when I bought him, he was a Real fighter. I have 4 cockerals, all in different pens with runs, and all have hens. I might post some pics when I get time... Hope he gets better soon.
