The other night, my chickens were all fine (I have 3 bantams of the same general age, that I got as older, feathered chicks). I have never had chickens before, and my other pets have all been generally healthy. Yesterday, I heard a loud squawk come from their coop (and while I now think that it was from one of my other chickens finding her grown up voice, I hadn't heard it before). Anyways, my beautiful orange and black hen was on the floor, and couldn't get up. I have her separated from the others, and she seems alert, and is eating and drinking normally (eating with gusto). She cannot stand or move her feet (though if you pick her up, she pulls her legs up to her chest). She keeps fluttering her wings and winding up on her back, so I have to flip her back over. I've researched a little and come up with suspecting either Marek's or Kinky Back (though I don't know if that occurs in bantams or if she's too old for that to have not caused problems before). I'm treating her with hypericum and tetracycline to rule anything out. She's had no change at all in the past 24 hours, and am wondering how long I should give her to attempt recovery, or if I should get her euthanized. I feel horrible. She doesn't appear to be in any pain at all, but it's not fair for her to be in the condition she's in. Is there any hope for recovery at this point?
