So far so good this year, but last year had a latebred hammered by a cock that had got in the wrong box, it was the worst I had seen, my man wanted to dispose of him but I asked for a few days to see if we could get any healing, salt water bathed and then propolis applied daily, he's now a cracking young cock looking forward to training him this year. I use propolis any time we have an injury with the birds, also on a hen that pulls her own feathers at the start of the moult each year, works a treat.
