Your chickens are so cute! Mine really like edible toys, like a head of lettuce or a pumpkin. It will last them all day and they have fun picking away at it. They also LOVE when it's time to get new hay...they play on the bales for weeks. I know what you mean about feeling guilty eating their eggs, but I look at it this way: the chicken would be laying the egg whether I ate it or not. So if I don't eat it, it would just go to waste. If you don't have a rooster, your eggs won't be fertilized anyway and there really isn't anything to feel bad about. They are proud of their eggs and I am proud of them too lol
