Ok, so here is my dilemma. Ive had hens for about a year, and recently introduced a Salmon Favorelle Rooster to the flock. They all get along, and the roo has had his fun with almost every hen in the flock. How do I knwo they are fertile, hatching eggs, vs non fertile. Ive candled them after takign them out of the boxes, and I dont see anything. I recently bought a incubator. I have incubating what i hope are fertile eggs, but I candled them after 3 days, and i dont see anything that makes me think something is going on. So how do i really know if the eggs are fertile. I assume the roo could have his way with a hen, and still not fertilize an egg, right? Am i missing something. i would really like to know the eggs are fertilized PRIOR to puttingthem in the incubator, that way I know. any help is helpful...thx!!
