Well we gave her 1cc around 6:30pm and then left for a meeting. Just got back and she is gone.
Well, that sux. With her going that fast, there's a good chance it was Marek's Disease instead of a vitamin deficiency. You would have to necropsy to know for sure. Vitamin deficiencies are treatable if you catch them in time, with Marek's, there is no treatment.
Just checked YouTube, they have chicken exams, necropsy. I put in Neocropsy on chicken for Mareks I got several. I have not watched them yet. I have the belief that knowing is always good, sadly animals can not tell you how they feel, or were it huts. They hide illness.
