I have a few questions that I would very much like clarified.
1. When you guys are choosing stags and cocks to keep for breeding what is it that you are looking for physically?
I'm not concerned about physical to much aslong as it's acceptable that doesn't decide if they are all business or not. In a perfect world I Don't want to long a shank with no thighs to back it up the thighs should be more rebust and where all the good comes from, well boned and not fragile, I don't want to long of a back or to high of a station, I want clear well positioned eyes that can see very well and miss nothing. Above all else if it isn't game it isn't worth feeding. If a stag hasn't shown me to be worthwhile by 8/9months meaning he shouldn't be running around with other males at all it's getting culled idc where it came from or who's names behind it.
2. Same question for pullets and hens.
You have to watch them I believe a good hen is worth quite a bit. Relates to stags in a big way.
3. Will you guys keep a stag/cock but not use him for breeding? What determines if you will use the cock for breeding or just hold onto him?
Once you've culled what you don't see fit you'll grow the stags out to cocks and reevaluate at a later time.
4. Not really a question, but if any of you guys could post a picture of a bird that would get culled and one you would keep, and identify why you’re culling the one bird and keeping the other.
Thank you.

Sure can't once a cull it's culled.
