As one who breeds the WBS variety exclusively, I'll give you a few things. To be honest, it's late and it's been an extremely exhausting day so please forgive my brevity and don't take it as a lack of responsiveness or attention to your questions. I'll be back home (and back with my birds!!) on September 1st. So if you'd like to email me after then, perhaps I can provide more info. I'm also happy to take calls and help if I can too.
First let me say that I'm not even going to address the most important trait - which is Type - because no snapshot in time can accurately judge Type. So I'll just address various colors or other obvious things I see. Also, wrt to W & BW, and especially the males, they can often be very hard to make your choices from until they're almost fully matured. Second, If it's good (i.e. nice leg color) I'm not going to mention it. Only those things I'd cull for. Having said that, here's a couple of things about the cockerels:
1) Cockerel #1 seems to have some brown barring in the tail feathers. He also seems to have excess fluff at the base of the tail now. Both of those may disappear as he gets older but I doubt it. Same goes for the hackles. You will see them lighten up tremendously as he gets old. That goes for all the cockerels so I'll just say that here. And I'll also just say here that if I were you, I'd grow them all out and keep some meticulous records so you can learn what changes and what don't.
2) Cockerel #2 is pretty good overall at this point. I see a little fluff at base of tail but not bad.
3) Cockerel #3. You can cull that bird now or mark him for the freezer. Extremely poor tail color, poor leg color, poor primaries, comb is too big for his age. Never seen anything like him.
4) Cockerel #4. Not too bd. I see a little too much brown/red in his tail and I'd keep an eye out on that white in his breast feathers. Leg color is a little light but acceptable.
5) Pullet #5. Not bad. A little dark overall but acceptable. Pretty good black in the tail and I don't see any ticking in the hackles.
6) Pullet #6. Overall good but notice the difference in black in the tails. Here's where you have to grow them out and make your choice based on an already established breeding plan focused on one or two specific traits you want to improve and/or get set.
7) Pullets #7 & #8. Pretty much the same comments as #6.
Sorry, but I'm getting pretty tired. Hope that helps though.
Btw, Samouw, I don't recall ever having any W or BW chicks with that much of a pronounced "dot" or "strip" on the head. I've had 'em with dots but certainly not that big of a stripe. Also the chick at 1800 has got a pretty dark back. I hate to tell you this but I think you've got something in your chicks besides W or BW. Also, if that 5 Day Old chick is still walking on his elbows, you might as well cull it. And it's way too early to tell a male from a female for W or BW.
God Bless,
Thank you so much for taking the time to reply! Cockrel #3's legs are not that light. The sun was lighting him up a bit. But now I will know what would be too light. When you say poor primaries, what does that mean? I think I'll keep him for now. It will be interesting and informative for me to see what changes on him, and what doesn't. My husband has always called him, grumpy old man. He's not mean or grumpy, just looks like he would be, lol. I'm assuming there is a more specific SOP than the one on the ABC site? Something specific to the W and BW's? I'd love for my husband or I to get out and do a show with some of our birds eventually.
