Thank you for this very thorough explanation - LOVE IT! I especially like that you provided your description of what you feel a good mate would be for this male in order to move the breed pen forward. Although this is not one of my breeds, it's ALWAYS helpful to read feedback that is so thorough such as yours!Ginny has asked me to comment on this male as he is descended from a hen she hatched from eggs I sold her several years ago, so here I go. (Note, this is being done on only one cup of coffee, so if I miss something, don't string me up please.)
Visually I like this cock bird a good deal. His color is quite nice, with no speckling or bleeding through in the body or the hackles. I believe she said he had good slate bar, always a good thing. I like that his tail has retained a good green gloss, some birds trend towards maroon, which is less than optimal. His legs seem a little short, but that's not a huge problem, given his breadth. I like his front especially, he's nice and broad in the chest, which is a very good thing. His wing carriage seems correct, although Ginny did say he's got some odd thing happening with the feathers there, not sure what that's about. I guess I'd see if he threw that in his offspring, and if he did, I might take him out of the breeding program if so, as that might be a twisted feather sort of issue.
His weight is low, he should weigh 9 pounds. So that's a problem. If he were pen bred to large hens, and the offspring were bigger, that would fix that issue.
His comb is a little large, but believe me, getting a perfect pea comb is HARD! His wattles seem correct, as does his eye color from what I can see. All in all I would probably keep this bird in my breeding program if I had large/heavy hens to breed him to, and if he felt right when I evaluated him using the ALBC charts (I hate doing photo evals, but this is the best I can do here.)
Hope this helps.
