I have a silkie hen I'm treating for wry neck with vit e and b1 complex. She doesn't really eat or drink much on her own so I've been slowly syringing water and giving scrambled egg yolk. I've tried mash and even flavored it but she shakes it out her mouth every time. She's so skinny now and I'm thinking shes not getting enough with just the egg. Would it be ok to give her Exact Formula? If so how much can she get per feeding, per day?
