Weird question. So I am raising some red sex link hen for the first time and dang, those girls can lay eggs. Anyways , recently I was gifted 3 roosters and I introduced them to my flock, currently only consisting of my 11 red sex link hens. They all get along well, and I notice them getting "it" on the other day. Which made me wonder, would the eggs the next days be fertilized, should I wait another day before I start collecting eggs to incubate? How many eggs do I expect to be fertilize before they start laying unfertilized eggs again?
