Ok...I've posted on this before, but still have the probelm. My girls started "molting" around Nov, and never got their feathers back. Some have small bald spots above their tails and on the front of their necks. Some have huge bald spots and naked necks! One looks more like a rubber chicken then a real one! I've tried DE & Sevin. Finally took the worst one to the vet. My country vet won't see chickens. Had to take her an hour and a half into a bigger town to a "bird specialist" who admits she dosen't see many chickens either, but would at least agree to see her. She looked at feathers and skin under microscope and could not find any parasites. She looked at poop and still could see nothing, but on the advice of the head of the poultry dept at UC Davis suggested worming with ivermectin bovine solution. Does this sound right? I have VERY small seringes and instructions to give each bird .01 cc for every pound of weight oraly. I am getting ready to do that at bed time tonight. I know I probably need to throw away the eggs for a while. Anyone know how long? Any other suggestions???? Thanks!
