Try watermelon Mine LOVE it!! I gave mine the rinds with some red goodies still on them They eat them down to the skin.Their favoritetreat so far ...besides grass! Also cereal (maybe not the sugared kind)corn flakes, shredded wheat, cherrios puff rice oatmeal.I do crush them up really tiny mostly.Oh yeah and spegetti started mine on it as a first treat. ,.I haven't tried any of the things your hens like, so maybe I will just keep trying new things and find out if they like them. For some reason I thought fruits and veggies would be a given. Today was a no to apples. I tried the black oiled sunflower seeds and they didn't like them either. Funny, they will fight and steal earthworms out of each others beaks though, so go figure....maybe they will like cooked spaghetti as a treat! Thanks for getting back to me, I appreciate it!
