i have a 10 week old salmon faverolle pullet who I have noticed a few times now she puts her head between her legs in a sort of frantic episode and walks/runs backwards, like she is almost going to fall over. It sounds harmless but it looks pretty frantic.. My 9 year old started balling watching her do this, wondering if she was okay. After she calms down a bit it's almost as if she can't look up wards for a while.. It's so strange. Is this just some weird thing or could this mean something neurological ? Or something else?
