@cree57i Final word from breeder, what a I do not and cannot possibly guarantee fertility or hatchability, that is just not how eggs work. It is impossible to know exactly how many or which eggs are fertile. I am sorry that your eggs have not developed but that is 100% out of my control.
Everyone who sells eggs rarely if ever do anything to make up for undeveloped eggs because eggs are just something they we have zero control over.
I am sorry but I cannot refund or replace for non-fertile eggs, I do not inseminate my hens, they are naturally bred. That 30+ % discount is the best I can do in this situation.
