i had a splash silkie about a month ago who kept putting her head between her legs like she was having a seizure or something she was about 2 months old i gave her some antibiotics and she stop doing it for a lil bit then again few days later then she would get so weak couldnt stand up i had 2 close calls of her dieing then one day went out and she was gone i tryed everything i could think of try to save her well today i went out and now her big sister is doing it, shes about 3 months old. why r they keep putting thier heads between their legs they r breathing fine, eyes and nose r clear, no pest i dust them once a month and i de wormed them last week so i dont understand why they r doing that. my other silkies (buff, blue, and white) r fine just seems i have no luck with my splash what should i do?! also i have 2 buffs who was born normal then as they kept growing their beaks start going crucked what causes that as well???
