Excuse my ignorance, but my neighbor told me something that just sounded strange to me, and I wanted to ask you all if this is possible. He has some mixed breed small / medium sized hens that lay smaller to medium light brown eggs. He wanted bigger eggs like mine so I gave him a big rooster when his last one got taken by a predator. I figured since his hens go broody often, he could hatch some eggs from my roo and his hens and those chicks may give him what he wants down the road. I talked to him a few days ago and asked how the rooster was doing. He said "he is great, he's got my hens laying those big brown eggs like yours." I asked again just to make sure I heard right, and he said it again. I assumed that the type of egg a hen lays was based on her genetics, but will the egg being fertilized by a rooster change the size or color of the egg? Excuse me if this sounds completely crazy, or completely normal. I just didn't know and figured I would ask the pros. TIA for your help.
