I have 27 10-wk-old birds that I got from the hatchery as day-olds. They were all supposed to be vaccinated for Marek's. 5 wks ago (at 5 wks old), one of my BA pullets started having equilibrium problems. She was having trouble standing and walking, just flopped around, skittered sideways, fell over, tipped on her nose, etc. No injuries, mites, lice, fever, congestion, or any other signs of illness. We tried vitamin E/selenium, CoQ10, yogurt (all in case it was a nutrient deficiency), with no change. I've tried several times to seperate her from the others, but she gets really upset being by herself (cries and thrashes around, spills food and water, etc.). Over the past 5 weeks she's had good days and bad days, but as a whole hasn't gotten any better or worse. She's never seemed to be in any pain or acted depressed, ate and drank well, and seemed to compensate well for her mobility issues. The only thing I could figure is that she must have suffered some kind of spinal injury or stroke. Seeing as though I'm not a breeder or commercial farmer and I don't mind giving her extra care, I figured (as long as she didn't seem to be really suffering) I would just raise one "special needs pet". However a few days ago things started to get worse. Although her stilted gait has improved slightly, she now seems to be having trouble controling her neck movements, which is making it difficult for her to eat and drink. I also noticed she's getting some redness and swelling around the feather folicles under her wings. Then, day before yesterday, one of my EE pullets (10 wks old) started having similar problems. She doesn't seem to be as severely affected as the first one, but is definitely staggering and can't walk even a few steps in a straight line. This morning the EE was sitting in the "classic Marek's pose", with one leg forward and one leg back behind her. I've poured through books, combed the internet, and searched posts on the board trying to get as much information as I can, and this just really seems like Marek's to me. So all you experts out there - or even anyone who's had any experience with this disease - can you help me to understand a little better? I've read that the vaccine isn't 100% effective - that about 5-10% of vaccinated birds still get the disease, and that the vaccine can't protect against all strains. Has anyone ever had a confirmed case of Marek's in a vaccinated bird? Is it common? How reliable are hatcheries when it comes to vaccinating chicks? Is it possible they really weren't vaccinated? Or vaccinated improperly? Or that there was a problem with the vaccine? If all of my birds were suppossedly vaccinated, what are the risks that the rest of them will get sick too? I would also like to hear from anyone who has a bird that's survived Marek's. How long did it take for them to recover? Tilda (my BA) has been sick for 5 weeks now. Is there any chance at all that she will recover? If she does, will she always need special care? If there's really no hope then I know I need to put her down, but if she has any chance of living a decent life I'm all for giving it to her. And finally, is there anything I can do to help these two get better? I've been making sure they both have food and water in front of them at all times, checking on them every couple hours, and helping them to get around when they need it. I woudn't mind paying a vet bill, but I've called around and I can't find a vet in my area that will even see a chicken. Sorry this is so long, but I'm just at my wit's end trying to figure this out. Any and all help and advice will be greatly appreciated.
