Some excellent points. I maintain only 4 breeding pens of RIR, a trio in each pen plus a dozen or so who didn't make the cut who are just layers, and an extra backup cock for each pen. Haven't counted but, for breeding purposes those numbers aren't bad. I'd like to get my breeding project birds down to those same numbers within the next year and a half. But MY RIR line is a great line and all culling is knit picky.
However, my genetic project is at peak required space right now. I have F1s, F2s, BC1s, BC2s, and am working on the next generations from those. AND, to this point, I have two distinct, unrelated lines of each of those groups (because until recently no one else was doing this project the way it needed to be done imo). By fall of 2016 I hope to have only enough for 4 distinct breeding pens, but you have to cull really deep to get that far. And frequently you can not really realize what you had and can cull too soon if you aren't careful. Those breedings where you realized that that step forward you took has created two steps back? You're better off backing up one step rather than willingly taking the results of the wrong step forward.
In short, what I'm over wintering this year is not an every year thing. It's a means to an end, and finally that end is in sight. If all goes well, that end won't be the headlight of an oncoming train. LOL
And it's nice that someone else is really now taking this project seriously. I now have some of his genetics and am taking him several pullets when I make a trip there in 2 weeks
I certainly was not being critical. I only wish that I could keep those kinds of numbers. It would be nice. There is a lot that I would like to do or try.
I get you on the project. Sometimes you have to make a mess to fix I mess. I get that to.
