hey everyone! just looking for advice on incubating! we always have tons of eggs and just bought an incubator just for something fun to do with all the eggs! we currently have 3 roosters living with the hens, how can we ensure that we are only putting fertilized eggs in the incubator? could we just assume or should we do a full on breeding session and then monitor the eggs layed by said hen? any advice would be awesome thanks!
