I think this is very relevant. It's been something my breeding partner and I have talked about a lot. I gather there are some HUGE New Hampshires out there, and she breeds those, too.
We specifically discussed the issue of oversized birds here at my coop when we had our first breeding group team meeting with our Breeder/Judge consultant. I don't show (at least not yet), but I gather there is a trend toward larger and larger LF in the show ring, with the judges seeming to prefer the bigger birds when all else is relatively equal. So far, we've been NOT wanting to go too far over standard in our line. I don't have issues with that as so far my birds have been a tad on the small side -- my breeding partner has some bigger birds. But I can tell with both the pullets and cockerels this year I'm getting bigger birds too, so started wondering if I should cull the oversized birds.
I was running around playing hostess during the specific part of the discussion where oversized birds were discussed. The consultant seemed less concerned about it than we are ... says as long as the birds are sturdy enough to perform as described in the standard for their breed, oversized was okay in his opinion, as it shows so well, etc. Size is more of a priority with the bantams. But with the LF, he suggested perhaps improvements in feed ingredients and management strategies accounted for the size potential for the breeds being more fully realized, so it doesn't really alarm him. But I didn't really get to cross examine him on the topic (I intend to at some point
).
We have spent most of our assessment time going over the structural integrity of the birds. Wings & legs, keels, pelvic bones. The first thing he showed me was how to really look at the wing curve and joint for indications about the stability of the birds' frames. Very cool ... wings have been my priority as there were some birds with really weird wings in this line. And the way the wings feather makes them look very odd during certain points of their grow out, so we learned about wing feather growth, too. Sure enough, the ones we noted "bad" wings on also had knock knees. We marked them as culls right there. We found one in my flock with a bad keel, which he said could be a management issue due to the roosting situation, and that we should lower the roosts to eliminate that factor. I'm not sure I understood the connection between higher roosts and crooked keels, but I'd been planning to lower the roosts in the cockerel coop anyway. Now it's done.
Some of the roosts in our coops were installed as a "surprise" to me, and I thought they were too high from day one. During daylight hours, when the roosts are empty, the birds seem to have no trouble hopping up & down. But as the birds mature, and especially now at dusk, the birds have started fussing about going to bed. With the lower roosts in the cockerel cage, bedtime goes much more smoothly. I think I'm going to lower some of the roosts in the other coops where the birds have been fussy & slow at bedtime. I'd really rather have the birds sleeping on roosts than elsewhere. Less fussing means more cuddling, which will be good as the nights get cooler.
