Yeah, I'm lost with this strangeness. Just gonna report what I'm seeing and maybe someone else has seen it as well and can comment. I bought in 21 black giant chicks in April from a local auction. Price was cheap enough. Didn't lose any chicks, everything going as it should, then a month ago I acquired 11 more black giants from a lady down the road give or take 2 weeks difference in age as my birds. So 32 total at this point. Not long after I got the new birds I lost my first BG for what ever unapparent reason I thought nothing of it. Then a week later I started losing birds at a rate of 1 a day all BG. So then my curiosity started getting the better of me. Not sure what was happening so I started necropsy on birds. Absolutely so signs of anything so not quite sure what's happening. I have a load of different breeds (RIR, amerucauna, leghorns, EE, Marans, bb reds, Dominique, etc) but not one death from any other breeds. Only in my giants. I watched one giant today that was really spaced out. She seemed to have a nervous tick happening with pretty bad coordination. She kept picking up her feet and stomping the ground. Any ideas? Open to comments, thanks.
