Hi BYC friends, About half of my chickens have some form of black spot on their combs, and the Roo on his wattle. Pictures included. Flock appetite and drinking is normal, as is excrement. I feed a high quality organic non-GMO freshly milled 16% protein mix. I have had three ducks in the same coop with my chickens. Recently I have noticed the ducks are fighting with the chickens, and picking on them a lot. Especially picking on the rooster. I am keeping the ducks separate during the day, while I get a safe place set up for them for night time. Any advice on whether or not these marks are from fowl pox, or maybe just being picked on by the ducks, is much appreciated. This coop has nine hens, one rooster, and the three ducks (two of the ducks are male). Thanks in advance for any advice based on the photos I provide!
