We just started getting 4 eggs a day from our flock of 9 hens that we've been raising for 6 months.. I noticed the other day upon cracking open the eggs that several of them had what looks to be the appearance of a bullseye on the yolk, so it made me suspicious.. especially of BO who looks different from her sister who was purchased at the same time from the same store.. Would you say there's a possibility that this is a rooster? The BO with the larger/darker comb is the one I'm suspicious of. Thanks in advance for your help "suspicious hen?" Pretty sure this is for sure a hen rooster? Our hen rooster?
