The birds like the plastic tub box in the hutch for laying their eggs. They do not like the cardboard box beside it. They kicked all the wood chips out of the cardboard box but always leave some in the other.
Edna (formerly Edsel) is the star athlete. When I hold out a jumbo mealworm, she darts in, jumps up and grabs it while the other chickens are still eyeing it, trying to figure out what to do. Even when I'm trying to offer the worm to someone else or holding it low so that Punkster and DartMouth can see it from under their top-knots, she grabs it first. Yeah, she's my favorite, even though she doesn't lay green eggs. I like her style.
Besides, I only want to spend so much time grasping a large mealworm between thumb and forefinger, watching it writhe around with its short legs waving.
