Triple antibiotic will work.
No bleeding today but I had to isolate him from all the other roosters until roosting time. The first thing he did this morning when he got out of his coop after a drink was look for a fight with one of his class mates. Until now there has been no fighting between the white giant boys. They have been even better than the Delaware boys that don't fight at all now. Even the two Dark Cornish boys don't fight with any other cockerel. I have about 20 RIR cockerels the same age as the others that won't to spar with any thing that moves. That's ok as we are 90% ready for freezer camp. The wounded White Giant boy was one of three that went into his coop and got on his roosting bar. Where the rest are no one knows. At day break they are out chasing bugs where I can see them out the kitchen window. 0 Dark Cornish are in their coop. I have a plan to stop their foolish ways before a predator has a dinner on them. I had 13 and am down to 10 dark Cornish and I'm not happy about that.Just clean the wound really well with warm salt water and apply the triple antibiotic.
Is it just his ear lobe that's injured? If so, the bleeding should stop quickly. The ear lobes, wattles and comb are very vascular and bleed a lot but it usually looks worse than it is.
