Harlie has been the stubbornest animal I have ever met regarding trying new foods, she was fed all seed diet before we got her, I've tried every trick in the book over the years repeatedly, including eating in front of her, making toys out of the foods, cooking it in various ways, cutting it stupidly small, restricting her food, even just feeding her one meal apart from the new food, she would sooner starve
This was all to the point where she wouldn't even eat soaked seeds, even if they were only slightly damp. I have no idea whats caused her to change her mind on this particular day but hopefully its the start of something good.
