I'd like to know how young a rooster is before he can fertilize eggs. I have Seabright bantees that are about 7 months old. I put 18 eggs in the incubator 8 days ago. We incubated 8 eggs from normal size chickens and they hatched fine, but these look like they might have blood rings around all of them. I believe my Seabrights are old enough to fertilize (from their actions they're totally ready), but believe there's something wrong will all of the eggs, they just look different from the ones before. I've been reading on exploding eggs and blood rings and must say, its really got me concerned, even tho I smell nothing. Any ideas or suggestions? by the way, I have 2 (a golden and a silver) seabright roosters and 5 seabright hens (4 golden and 1 silver), and am getting 3 to 4 eggs a day.
I also have 2 rocks from the ones I incubated. One definitely looks like a rooster, one looks like a hen. I noticed my hen was getting pretty aggressive with my bantees and had to separate them, then noticed my hen was growing...not the rooster. Looking at the posted pictures of the rocks, my "female" could very well be a rooster. Unfortunately, I will have to get rid of them before they hurt my others.
