We have this chicken who is bizzare from the start. Shes a mix of polish and spitzhauben. SHe has always been a "freak" with how she jumps when touched if she does not know you are there so just her manner in general, nothing to make us think she is sick, just strange. She never developed any tail feathers! Her butt is round. She is about 7 months old. We have a guinea who no chickens like. Every one says, look, pickels, (the polish mixes name) and the guinea are friends. I say, no, they are not. Pickles does not even see the guinea- long feathers over eyes. Soon as she sees him she jumps like a freak and takes off. She even has a run that is a riot. Shes a loner chick and one of our favorites. Anyhow= she was acting strange the last couple days. Today, she is falling over to the right and bopping her head in the strangest way. I dont think its crook neck- its not crooked, but more bopping and she just cant stand up. Any ideas?? Thanks
