Can you keep two of them, even separately, in case the one you initially prefer, gets mean?I have 2 Bielefelder cockerel's that I have been growing out over here. The one that's the oldest I hatched on January 17th of this year and has yet to let out a crow. My other cockerel that I hatched out on February 18th hasn't crowed yet neither. If they do, it's ok though because I can have rooster's where I'm at, and I'm going to be breeding and hatching later from my Bielefelder's.
