I agree about the chicken. I never give mine poultry, but if I could hunt some good healthy phesant or grouse in South Dakota then I'd give that to them.
I'm not sure I can agree about not giving rice when they are sick. I've done it many, many times with fosters and it has worked beautifully.
I'm sure she knows her stuff, but be very careful about buying the vitamins and such from her. Remember, they make a lot of money selling items that you could get much cheaper elsewhere, and they may not even need some of those vitamins..........it's a "won't hurt" type of thing.
Good luck getting your baby straightened out once and for all.
