Mine hate yogurt, won't touch the stuff . . . except for one, who goes crazy for it. The treat that never fails to turn into a feeding frenzy is a nice handful of roaches. They like them even more than the phoenix worms and crickets I catch for them! The jury's still out on veggies, but they'll eat no end of grass. Boiled eggs are a no no, but if I prepare them any other way they go crazy. What's your chickens' favorites? Dislikes?
