I hatched out 20 EE mutt chicks this spring. I only planned to keep 5 or so and sold the others to a friend for real cheap. Tonight he calls me and say that all of his chicks (15) have little spurs. I checked mine and all of mine have them as well. Did I hatch 20 roosters?? 7 are 7 weeks old and the rest are just short of 4 weeks old including the ones I have. What are the odds of this or do they all have little spurs at this age and I never noticed. BTW they are from 4 different hens and 1 rooster.
