I had a black copper maran do something weird. A while back, we had a really bad series of rainstorms and he got sick. We took him to the vet, got some medicine, and after a week..he stopped sneezing and his runny nose was gone. But he also stopped crowing (well, he'd try, but there wasn't any noise).
After a while, his crow came back, but it sounded really nasty. We just figured that maybe his voicebox (or whatever it would be) got damaged from when he was sick.
But then I started noticing that his comb was getting darker. I decided to continue to medicate him every so often with the medicine we had leftover.
After a while, his comb, wattles, and his legs turned purple. I could not figure it out and couldn't afford another expensive vet visit. This lasted for about a month. One morning, I went out and was looking at him and honestly considering putting him down. He didn't act sickly, but I was really worried about the purple and the fact that his crow was so yucky sounding still. I went out for a little while to run errands. When I got back home...he was dead.
He shared his pen with four other copper maran ladies and now I'm noticing that some of them are getting a little bit of purple on their combs. They haven't been sick anytime soon, but I'm wondering if they have a disease or something...
I wish I had pictures of the rooster. Thankfully, the marans are all sectioned away from the rest of my flock and have been since we got them.
