I've lost 2 chickens. 1 being a Rhode Island Red and the other a white silkie. One passed last Friday and the other this Friday. My first one that died I noticed she wasn't herself running around like a spaz her comb had this nasty stuff on it it was mucusy. I brought her in she layed down and slept for an hour then she had like I seizure and then died. My white silkie passed this morning and she was in the same postion as the Rhode Island Red but she was fine last night when my husband went to check on them and close them in for the night. I found her in the coop. The rest of the chickens are fine running around eating drinking mouthing off like normal. Any body have this happen?
