Our chickens practically like everything. They're little piglets. They each have different tastes though. One loves bread and pasta, but turns her nose up at lettuce and cabbage. I say it's because she can get greens in the yard anytime, but can't forage for bread. Greens are not a treat in her eyes. We have a few who like cheese and others who don't. 2 out of 5 like popcorn and the others won't touch the stuff. They're all weird about different vegetables. Each hen will eat certain veggies but won't touch others. And, none of our hens like yogurt or anything wet like that. I'd seen pictures of hens eating yogurt and applesauce and the like, so I tried it out. Wouldn't touch it. They thought I was insane.
