Hi Angie16Hearts I have 1 Welsummer hen, I am certain her eggs are fertile, however they would be a mix of something else, either Egyptian, Barred Plymouth Rock or my Big Comb rainbow colored guy (not sure what breed he is). But I too live in central CA and could give you some fertile eggs, I have other breeds of chickens as well, of course all eggs would be somewhat mixed, maybe with the exception of my Barred Plymouth Rock hens eggs.Wow, what a wonderful thread! You peeps are very kind ! I'm sorry to hear other stories it's sad! Never in my life would I have thought I would miss a hen! I know it's a dogs instinct. It's just the dogs who have not been treated right and or are breed for fighting. I feel bad for the dogs as well. When a owner can't be responsible. Then we all loose our little friends. As we all know Intel you have chickens you don't understand the love you put into your flock
