I just discovered 2 of my cochin roosters swollen feather folicles and they are quite red, though not bleeding. they have been pruning themselves and taking dust baths, but upon inspection I found no sign of mites (or at least visible ones). I also noticed that they have red skin near their breasts and last week none of this existed. Otherwise they seem perfectly healthy. In researching in my chicken health book all I could find was swollen feather follicles under a symptom of Merks. Anyone think that this might be the prob? In addition I have a hen (she is 2 years old)that suddenly started limping on one foot. The bad foot is curling at the toes and she is starting to drag it. There was a complete drop in egg production, then after 4 days she laid an egg. The egg shell was healthy looking, and when I broke it open, there were no blood spots or anything unusual- it looked totally normal. Any ideas on if this could be a related thing? My hen has no swollen follicles or redness like my cochin roosters do. I only have 11 adult birds and have (5) 2-wk old chicks. The chicks are perfectly fine as is its mom. Could this be Merks disease? Should I have my hen culled (I have an appt. to bring her to the vet, but they are not avian specialist.
