I don't know how it happened.. I've had a special chicken (growth retarded), since August 1st. He/she was around four months old when we got him. Hasn't grown an ounce since that day. We have wormed all of them, as a preventative. They've been treated for parasites (mites, etc) with sevin dust. We have lost one other to this same mysterious cause. Both from the same breeder. He's had the following issues: Poor coodination Can not fly from even a foot in the air to the ground. Very skinny Sluggish Had wry neck (possible, not 100% sure, though poly-vi-sol fixed the circles he walked) Is there something I'm missing? What could possibly cause such a sudden death? I'm so heart-broken. I've had my chickens for only 3 months, and have already had to bury two..
