On April 2nd of this year, I purchased 6 EE pullets from the local feed store as day olds. At about 12 weeks it was becoming obvious that Petunia was developing a very bright comb and some saddle feathers. A few weeks later he started crowing and attempting to mount his brood mates. He has not developed spurs at all. The other five ladies are now all laying. An old chicken keeper from back in the day told me that if he was sexed as a pullet, and developed as a roo without spurs he is probably sterile. Any feedback on this? Old wives tale or some basis in reality?
