Have you had any of them tested for coccidosis? That is about the right age for that to happen cause they are tryin food and maybe a bit of browse and grass for the first time.I have had repeated cases of enter otoxemia over past few years in kids. I have saved some and lost some, but getting frustrated with how frequently it occurs. What should I be doing differently to prevent. Kids are usually 3 to 10 weeks. Any ideas?
