I'd greatly appreciate your comments on this 6-week-old chick: color, crest, type, whatever one judges a chick on. What would you think if you saw her in your flock? No holds barred, and many thanks.

p.s. Is a chick of this age's coloring likely to change significantly? For instance, can one tell salmon from chestnut at this age? Thanks again.
1)
Crest Type. This look great. Not too big, not too small.
2)
Crest Color: A lot of the birds in the USA have the black cresting. My wife loves the black crest so we will probably keep some for the laying flock, but the correct color for the UK standard is a brown or gray color on the Hen with he additional allowance of some chestnut on the Roo. So...great color too.
3)
Whatever:
a) The comb looks crooked, but this is a small thing. The hens combs are allowed to flop after the 1st point anyways so this should be fine.
b) The hackle is light. I am still learning how to identify correct hackle color, It may have some gold I can't really tell for sure.
c) Legs are yellow. So that is great (some are willow/green or pale colored)
d) Can't really say anything about the body type. All I remember from the standard is that they are supposed to have a prominent breast and that they should be wider at the shoulder than at the tail in a wedge shape.
e) Beak is yellow: It has some dark streak through it, but this should go away as the bird matures ans is a small item.
Yes, I the color will change a ton in the next year. It is looking like this one has the correct salmon coloring on the breast. Eyes will eventually change from black to orange or an orangish red.
In summary...the Crest, Comb, Barring, and Cream color hackles are the things that are easiest to see in a photo and the hallmarks of the breed. This pullet looks good in all of those categories.
