I have a hen (from this Spring's chicks) that has grown into a crooked little girl. She seems perfectly fine-just a bit askew. I never noticed anything wrong as a chick-just as she got older her tail seemed to be a bit to the side-but since she never had any issues other than that I didn't think much of it-but upon closer inspection I notice that her back is just completely bent weird...She never acted as if she was injured so I have to think this is just a genetic or something like that... I've read that too much protein can cause a back issue like that-but I gave them their chick food just like the bag said-until 16 weeks and then switched to layer feed...They also have freedom to forage as they want and I give them greens and some scraps on occasion. Is that the only cause of this (besides injury)? I can't seem to find any more info....she gets along just fine in the flock-she just doesn't roost up high with the bigger hens and roos... Here she is today: When we first got her-she is Chubby Cheekers (although we now call her Crooked Hillary haha!) Here she was as a juvenile, at this time she always seemed to have her tail down...but something I never took as a sign of anything.
