Hi
Sorry to hear you had to cull one pullet and now have another showing symptoms.
I had to cull one pullet in October with Marek's but I have 2 others that are surviving despite paralysis. One lost the use of her leg in Sept but has had no further degeneration and just hops about. It took her several weeks of tripping over herself to learn to hold that foot up out of the way, but once she figured it out her balance and coordination has improved tremendously. She has been living in a brooder with the other pullet with it as she lost confidence within the flock, but just recently she has been wanting to be out and when I come to lock up on a night she is up on the roost with the rest of my flock. My hen house is an old stable and they insisted on roosting on the old hay hecks, so the roost is probably about 5ft 5 off the ground, which tells you how agile she is.
The other had her first attack in Sept/October, fully recovered after a week or so and then had a second attack in Jan. She is still paralysed but can walk in a fashion but her left leg has a tendency to get left behind so she is very unsteady and she has also developed wry tail to a small extent, perhaps as a result of trying to use it to counter balance. Both look healthy and eat pretty well although I have a tendency to give them a lot more soaked mixed corn than they should have as they eat that more enthusiastically than layers feed and I decided that it was better to ensure that they were eating plenty than to worry about the correct nutrition. I get an egg every 2-3 days from one of them, but I'm not certain which one is laying or if they are taking turns. Both should lay blue/green eggs, so I can't identify the origin from that. and never caught them in the act.
I've also had 2 cockerels that have shown the leg paralysis and completely recovered months ago.
I've got 26 other chickens under the age of 1 year that have all been reared together and so far no more have shown symptoms and most of the pullets are now laying.
Anyway, I really just wanted to say that, if it is Marek's, from my experience the prognosis is not as bad as I expected from my initial reading into the disease and if you are prepared to give the poorly ones a little tlc and patience, culling may not be necessary. Having said that, the one that I did cull had no quality of life and when I opened her up she had two huge tumours and would probably not have survived much longer anyway. I appreciate that I am by no means an expert on this and I am only in my first 6 months of dealing with it, but to lose just one or 2 to it out of 30+ chicks that were reared last year is less than many people lose to coccidiosis and certainly less than the number of chickens I have lost to dog attacks or accidents.
I really hope my post has given you a little hope and that your second girl will make a good recovery or at least hold her own as my little girls are doing.
Best wishes
