Are they good or bad to feed ferrets? I gave the girls chicken livers because i am still trying to get them to eat raw!! And Romy ate it! She actually loved it, and ive been giving her one a day for a few days now and the nasty stools are gone, and the number of stools are gone too (they were pooping atleast 10 times a day each!! My mom bought some chicken hearts and gizzards for them thinking maybe they would like that, and I havent given it to them yet I was gonna do that tomorrow, is it a good idea?
