Oh, I don’t think so, @JilltheTooth. I think the egg and the chicken are one, and that at some point the chicken entity gained an ability to become two while still one, and the second entity became separable.
Besides, think of it: chicken eggs, robin eggs, ostrich eggs, turkey eggs, penguin eggs, sparrow eggs, and all the rest—who do you suppose sat on the first ones until they hatched?
Not to mention frog eggs, snake eggs, sturgeon eggs, and all kinds of other fish and crawly things. Somebody had to build them nests or whatever. It’s not as if some major part of creation that had just kind of been humming along independently suddenly grew shells and waited to hatch.
Besides, there’s that Gary Larson cartoon showing a chubby, freckled youngster with glasses and an overbite, standing next to a chemistry set holding a test tube and wearing a stunned expression in the midst of an explosion of feathers, with a caption to this effect: “God as a teenager attempts to create a chicken.”
