My hen Hazel (RIP) a SS. Similar to your "Fattie" making that "crow" sound. She still layed eggs and did this occasionally.yup, that's her. i threw it up on FB, votes say she is a crowing hen or has gapeworm. i treated her with fenbendazole late last night, but i really doubt that she has that. no one else is making that noise or shaking their heads, she is not shaking her head at all.
