Thanks, sounds logical.
So when you guys have a good thing going, what is your cull rate?
One of my mentors once told me that there is no maintaining in poultry. You're either making progress or going backwards. For a given breeding 10-20% are going to be superior and worth breeding from to push your line forward. 10-20% are going to be inferior and should be culled, dead, period, removed from anyone's breeding program. The remainder are about the same quality wise, those are your show birds, your birds to share with others, your layers & meat birds etc. Still good representatives of the breed, but aren't going to push your program forward.
