It's hard to get it right, I am having issues at the moment with getting it right. I have tried different things, nothing too drastic change as I know this just upsets the stomach, I tried the raw recipe they were on, one didn't really like that, tried another recipe with a supplement, that was ok, tried it raw, then cooked, then a mix (but never to real success), then the original cooked, then the original without the vitamin b as the breeder said that is something they probably didn't like, it has been better, but not 100% yet, so am thinking the oils that I have in it is an issue...I am going mad with trying to get it right and like you don't want them to starve...but it's currently doing my head in! So I feel your pain, but don't give up, you will get it right (I find its harder with the two as they like different things
). I think as she likes the cooked chicken you could try mixing that with whatever you are giving and lessen the amount over time? Fussy little buggers.... Good luck!
