1) What type of bird , age and weight. Two silkies and one sick Ameraucana - all about 7 months old 2) What is the behavior, exactly. Lethargic and quiet; no diarreha 3) How long has the bird been exhibiting symptoms? Symptoms appear one day and the chickens died within the next day or two 4) Are other birds exhibiting the same symptoms? No symptoms in my other birds yet. 5) Is there any bleeding, injury, broken bones or other sign of trauma. No trauma. 6) What happened, if anything that you know of, that may have caused the situation. Nothing I can think of. 7) What has the bird been eating and drinking, if at all. Regular unmedicated poultry food, scratch, corn, some treats 8) How does the poop look? Normal? Bloody? Runny? etc. I saw a couple of poops in the coop when I cleaned it out that may have been bloody; hard to tell. 9) What has been the treatment you have administered so far? Cleaned and disinfected the coop; apple cider vinegar in water and yogurt; plan to mix vitamin powder in their water today, 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? Need to treat myself; I don't want them to suffer, but I cannot take them to the vet. 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use - closed coop (we are worried about drafts now so today we are closing off two of the windows - they will still have good ventilation, but it is getting colder); hay and wood shavings in the coop floor. Their pen is completely enclosed and covered; we have some hay scattered around there, too. Both food and water is up high enough they can't poop in it. We do allow them to free range on the weekends when we are home. Last Monday morning when I went down to feed them, one of the silkies was lethargic and not interacting with the rest. I brought her in the house. She was eating and drinking water, but was off balance and her feet -- while not paralyzed -- just didn't seem to hold her up well. No bloody or runny poop. She lived until Wednesday and then died. Today when I went to feed them another silkie was in the coop, not moving and barely breathing. My poor DH had to put her down. An Ameraucana was out in the pen with the rest of the chickens but not walking around and had her head sitting low on her neck and her feathers kind of puffed out. She was shivering. We brought her in the house and have her in the bathroom with the ceiling heater on. I gave her some scrambled eggs and some water. She is lethargic, but she did eat some. In hind sight, yesterday Fiona (the Ameracauna) did let me pick her up which is unusual, but I've read that when they are getting ready to lay they may be more friendly, so I attributed it to that. A couple of our other hens have started laying recently. Having a vet do an autopsy is really not an option. From what I've read online, I think I can rule out Marecks and (since there is no diarreha or bloody poop) worms? Any help or advice you can give would be much appreciated.
