Ok my girls are between 15-20 weeks. ...roughly. But I was out there today an noticed spurs on one for sure possibly a 2nd one. My question is could it be possible that they are rooster's that have not crowed at this age? Or do some hens get spurs? They are NOT full blooded and have lived with a rooster for 4 month's and there is a rooster next door crowing, if that helps.
