Preface: So, over the past week or two, I have been noticing that one of our hens (Nutmeg) has been getting these black scabs on her comb. She doesn't get picked on a lot (as far as I know) and we have no roosters. It has been as cold as 27 degrees (F) around here at night and their coop is not heated...however, I do not think it's frostbite as it's not only affecting the tips. After reading numerous posts, I was concerned that it might be fowl pox, although it doesn't really have any "bumps," just the scabs. Any advice would be appreciated! 1) Description: She is a half-EE mutt, around 10 months old, laying hen, unknown weight (but not skinny; a normal weight) 2) Behavior: appears unchanged, acting perfectly normal; 2.5) Symptoms: has several black/brown scabs on her comb, no sign of weeping or raised bumps 3) How long has she been like this: 1-2 weeks 4) Are other birds exhibiting the same symptoms: One other hen has a few small spots on her comb; the rest are normal 5) Is there any bleeding, injury, broken bones or other sign of trauma: No. 6) What happened, if anything that you know of, that may have caused the situation: No idea; see top paragraph 7) What has the bird been eating and drinking, if at all: Normally, as far as I know...she gets free-choice layer pellets, water, table scraps, scratch, and some free-range every day 8) How does the poop look? Normal? Bloody? Runny? etc: Normal, as far as I can tell 9) What has been the treatment you have administered so far: None; I will isolate her if you all think it's necessary but we do not have a place in which to do that... 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet: Just want to know what's wrong first. 12) Describe the housing/bedding in use: Four hens in a 4x4 coop, 12x11 run, shavings inside the coop, dirt in the run, free range ~30 minutes/day. They do pick on eachother occasionally, but I do not think it's enough to draw blood from the comb...See my page for pics of the coop and & run Here's the "front" of her comb... And the "back" Any help would be appreciated! Thanks!
