I have a flock of 22 hens and 3 roosters. This morning when I went to feed them two of the roosters were exhibiting very black combs. One of the roosters in an australorp and the other is a wyandotte-cochin cross. As far as I can tell they were both fine yesterday. The wyandotte-cochin also looks like his feathers have lost their luster. I checked all the other birds and they all look fine. Both roosters are acting normal. There is no chance that this is frostbite - it's been warm here. I've also looked at pictures of pox and the pox seems much spottier than this - it's like the combs have just completely changed colour. Any suggestions on what this could be or how to treat it? We HAVE had rain non-stop for the past four weeks which makes me wonder if this could be a fungus of some sort.
