I posted about 10 days ago about a pullet with a possible leg injury here: https://www.backyardchickens.com/forum/viewtopic.php?id=540066 Well, she is still with us, but not better, in fact she's worse. Now I'm thinking it's more like paralysis, as her other leg doesn't seem to be working well either and she not longer gets up at all. She is living in my garage in a box with one other bird, a young roo who had been getting picked on and had quite a bit of bleeding, so I pulled him from the flock to heal. They have been cuddling and "talking" and now when I take the roo out for a little exercise he calls out for her. It's very cute. Sorry- I'm rambling off subject here . So, she will still eat and can move herself around the floor of the box to get between the food and water- but she is losing weight (maybe muscle mass since she's not mobile) and she just isn't doing well anymore. I've come to terms with the fact that we will need to "put her down" soon. However- I just read a long thread last night about Marek's and I am concerned. She did do the "splits" when she was still getting up- one leg would slide in one direction, leaving her lying down in the splits. She has been very calm the whole time and doesn't seem sick otherwise and I don't see any other symptoms, besides the paralysis getting worse. It's been 10 days since I noticed her "slipping" and no other birds of my 14 have shown any signs or symptoms. And the poor roo has been locked up in the hospital ward with her- I really hope it's not something contagious! He has no signs or symptoms either, I've actually been wanting to try and re-integrate him, but I haven't wanted her to be alone once he's out. Part of me is thinking that if no other birds have shown signs it most likely is NOT Marek's... ??? But, I know I can't really assume anything. I've also read that all birds exposed (even with no symptoms) will be carriers and shed/spread the virus for life. So, this is very serious, of course, if this is the case, even though none of my other chickens are sick. I am trying to look into someplace I can have a necropsy done (for not too much money- my husband will kill me!) near San Diego, CA- so if you know of anywhere, let me know. I'm also wondering what the best way to put her down humanely would be if you intend to have a necropsy performed... are there certain methods you can not use (that would affect the necropsy)? I believe a friend of ours was going to shoot her, as he's done with his chickens for years now (I know it sounds awful and I don't even like typing it, he says it is a humane, quick way to "take care" of them). If anyone has any thoughts or opinions on this situation please let me know. The thing is, had I not read the recent large post about Marek's, I would never have thought of this- so I don't know if it's just my mind running away with the idea or not- I'm in a little bit of a panic. Thank you so much! ETA: The pullet in question is 11 weeks old now. The rest of my flock ranges from 8 1/2 to 11 weeks.
