In the past 4 days, two of my Serama cockerels have been injured by a 3rd. (The that one is now separated from the others) I brought injured ones in, cleaned them up with hydrogen peroxide and then antibiotic ointment, put them in a back entry way where temps are about 40 (its 15 outside) with treats, etc. Two of our hens are there and all seemed fine. Today the one cockerel seems to have developed an infection. Theres some pus on the wounds around his mouth and nares and for awhile both eyes were swollen shut. One is part open now.His comb and wattles are kind of pale too. I cleaned him up again but directions say not to put Hydrogen peroxide on eyes so I was real careful there. I got him to take a little water with electrolytes by pouring it into his beak from a bottle cap and got a tiny bit of scrambled egg in his beak. Hes in the house now, kind of lying down on a towel. He has been so quiet Im almost afraid hes dying. Is there an oral antibiotic I could get at Fleet Farm and how much would he get? Or could I give him a tiny amount of an ampicyllin pill (how much?). If I drip water into his mouth could I be drowning him? He does swallow it. Any help would be much appreciated.
