Sorry, I think I posted this under the wrong category, so re-posted here. I've been running a spiral breeding programme with three pens for three years now, so far so good. Now, though, it is time to retire one of my roosters, the best I've had, but none of his sons are as good as him. I feel like I'm going backwards in using one of those roosters, but I think I have to, yes? Does anyone have this problem? I presume I just have to go ahead as planned - or, how do you solve this dilemma?
