Hi there, a couple of weeks ago I heard a bunch of squawking and I found three of my young pullets with bloody combs and chipped bills. By the afternoon, the last one also had blood on her comb. I checked their coop but couldn't figure out what had happened. Now I realize that it was the pvc auto-feeder I had made - because there were still sharp edges and the holes were too small for their growing heads and combs. I took care of that, but now one of the bird's comb looks awful! Another bird also has some yellow spots on her wattles. Do you think that this swelling is because of an infection? Should she get oral antibiotics? Should it be lanced? I did put some topical ointment on it yesterday. The bulge is turgid but gives slightly when I press on it. Any help would be appreciated, thanks!
