1) What type of bird , age and weight. Americana, don't know age - maybe 2 yrs, don't know weight - she won't let us catch her, but she looks like she always has, no gain, no loss. 2) What is the behavior, exactly. She and my Buff that is 2 have been laying soft shelled eggs for about 3 weeks now. I have given them calcium in form of oyster shells from the feed store. They also get scratch and lay pellets. We give them fresh veggie and fruit scraps on occasion. 3) How long has the bird been exhibiting symptoms? About 3 weeks except for the blood I noticed in the coop and on her butt today. 4) Are other birds exhibiting the same symptoms? My Buff is laying soft eggs, but no blood. I also have what we think is an Austrolorp and a Plymouth Barred. They are not laying at all, and have really dirty rear-ends, but no blood. 5) Is there any bleeding, injury, broken bones or other sign of trauma. See above please. 6) What happened, if anything that you know of, that may have caused the situation. Nothing that I know of. 7) What has the bird been eating and drinking, if at all. Scratch, lay pellets, oyster shells, drinking normal as far as I can tell. 8) How does the poop look? Normal? Bloody? Runny? etc. Between the 4 chickens most poop looks normal although there are some poops that are runny. I have not seen any blood in the poop yet. 9) What has been the treatment you have administered so far? Nothing, because I have no idea what to do. 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? I think we can treat by ourselves if we know what to do. 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use Hens live in an A-frame coop with bermuda grass hay for bedding.
