I have a welsummer cockerel that has been somewhat beaten up by another cockerel (buff orpington!?) and he has a nasty looking slash in his comb. I am not sure of what the best products are for cleaning and disinfecting this.... never really doctored birds... Can I use peroxide? I have him on his own so it doesn't get messed with by the other birds but I think it may need some kind of ointment too... any recommendations? I would prefer herbal type stuff if at all possible but am open to using whatever is needed to get him healed up. Thanks
