I finally got a couple of roosters & want to start my first attempt at hatching. Yesterday was day one of introductions (roo's were busy!) I watched which ones were successfuly mated. So now, I wait a week & start takeing those eggs and as I understand it can hold onto the egg up to a week until I have the amount I want to put in incubator. (I wish I could just put them into the incubator a couple at a time) Is this correct? Any advice anyone?
