No point in contacting them...it was Mt. Healthy. In my experience with them in the past...if something goes wrong with their birds, it's your fault. Enough said. I have been advised to contact my State Vet and let them know of my concerns, but I think first I am going to check into testing on the carcasses. Frozen as they might be, if the retrovirus is present, it will be in all tissue in my understanding. Trouble is, right now, it is going to be sporadic contacting as I really, really have to get myself and birds ready for Winter. I am now stuck with doing the work of two people and even working from sun up to sun down, I'm not making it folks. I'll take and make the calls daily but will have to play phone tag unfortunately. Deb, how old and how soon are you going to be processing your birds? Where did they come from? Is there anyway you can keep a couple as long as I did? One good thing from what I have so far...Lymphoid Leukosis isn't as transmittable as Marek's is. Here's some things to watch for....funky green poops, that get better all on their own. I thought they were because of the heat we had, now I'm rethinking. Cocci in meaties, who ever heard of that? Never had it until this year and I've raised 4 batches of them before this. Expert? Heck no! Vigilant? Better believe it, I have Marek's here. I am just giving you the few symptoms that I have thought of today. Are they relevant? Your guess is as good as mine. I do know that the weird green of their poop let's me know of liver involvement. Okay, it's late for me and the sun comes up early still. I don't have any answers right now, just questions and suppositions. Neither does anyone any good. Without testing, it is all guess work and may not be a thing to worry about. Do I believe that? No, I don't. My luck doesn't run that way.
