I had to feed mine bits by hand before they became interested. I put 1/2 a head of cabbage out for them 3 days ago and today is the first time they have touched it. It takes time but they will figure it out. Not sure where you are so will assume that grass and bugs will dissipate as winter...
We have buffs and even after cutting off some kernels and giving it to them they don't seem to be interested. I will try banana's tomorrow. It has been an adventure in trial and error when it comes to food treats.
Well I gave them an ear of corn a couple of hours ago and so far they are showing no interest. Same with the lettuce ends yesterday. Silly girls don't eat many treats!
Mine seem to love Watermelon and strawberries. I have tried lettuce, spinach and yogurt and they wont touch them. Just gave them an ear of corn so we will see if they like that!
