Hello - - I have an 8 month old bantam cochin who was just a fabulous happy free-ranging hen until a few days ago. Here are symtoms: ~Cannot walk or stand at all (real trouble going forward - she just tips onto her beak). ~Head sometimes falls forward to the ground when she attempts to eat or drink. ~It's like she cannot eat or drink alone...I have to pick her up, put her in my lap and support her for her to eat. ~She is only scooting backwards on her feet. ~She has a full appetite..eating like normal. I have read it maybe a vitamin deficiancy.....can anyone help - - - What exactly do I need to give her? Any more advice? I have started her on the yogurt/oatmeal/egg yolk mash this morning AND I am leaving for the store to get Polyvisol w/o iron soon.... THANKS!
