Hey Y'all, [Back story] I purchased 17 Rhode Island sexed pullets hatched on March 3, 2020. This is my fourth set of sexed laying hens. I was nearby at my garden again early in the morning, when I heard the unmistakable crowing of a ROOSTER. Still, when I get into the chicken coop and/or the chicken run, they scurry to where I am not. So, I haven't really paid attention and looked at them closely. This morning when I gave them fresh water and starter/grower I paid special attention and looked them over. Sure enough, we gots us a rooster [surprise]. Now I need to determine if I want to keep the rooster or not. I only have chickens for the eggs and never had a rooster. There's only four benefits I can think of for having a rooster; protect the hens, eat, fertilize and listen to the nice crowing in the mornings. The neighbors rooster badly tears up the hens and they look terrible and have wounds from mounting. This spring around here there seemed to be a big shortage of purchasing baby chicks, especially the breed(s) I'd settle for for my purposes of just eggs. This has got too long already so to my question: If I buy an incubator and try and hatch my own for the next set; is there a way to determine what eggs have been fertilized and/or... Roughly, what percentage of eggs will hatch if randomly picked from the nesting box? I know I'll have to do some reading and digging around this forum to find answers to my questions. Thanks all!
