1) What type of bird, age and weight (does the chicken seem or feel lighter or thinner than the others.) All 5 are Ameraucanas, approx. 2.5 yrs old, not sure about weight, maybe around 3 lbs? 2) What is the behavior, exactly. Dark black/brownish spots on the combs of 3 of the 5 hens. One has a cracked area on her comb as well, and another has a small amount of blood on her comb (like a sore that hasn't scabbed over yet). 3) How long has the bird been exhibiting symptoms? A few weeks? 4) Are other birds exhibiting the same symptoms? Yes, 3. 5) Is there any bleeding, injury, broken bones or other sign of trauma. Nothing besides what I listed in #2. 6) What happened, if anything that you know of, that may have caused the situation. I don't know Maybe because it's been unusually cold this winter? Normally our part of NW Washington doesn't get lower then 30-40, this year it's been 20-30. 7) What has the bird been eating and drinking, if at all. Eating (Kalmbach's Organic Harvest layer pellets) and drinking plenty, and all have normal energy levels. 8) How does the poop look? Normal? Bloody? Runny? etc. Normal 9) What has been the treatment you have administered so far? Neosporin 1-2 times a day (the kind with pain reliever in it too). 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? Prefer to treat it ourselves but will do whatever they need. 11) If you have a picture of the wound or condition, please post it. It may help. Photos linked at the end (sorry they're not the best, my phone is too slow for their fast moving heads.) 12) Describe the housing/bedding in use Pine shavings mixed with D.E. and a layer of Sweet PDZ on the bottom. I clean out the poop and wet litter about every other day.
