I have a White Faced Black Spanish who started out laying huge eggs. I've read that they typically lay large eggs. She took a month long recess, and has started up egg-laying again. Now the eggs are small. This made me wonder: If a chicken that is supposed to lay large eggs lays only small eggs, what happens if those small eggs are incubated? Isn't the chick genetically programmed to get a certain size? Once it fills the egg, can it no longer grow, resulting in death? Or does is hatch as a smaller version? Or does the size of the egg make no difference? Does anybody know?????
