What is he?

[chickenlover54]

you can tell how old a rooster is by the length of his spur. that rooster is atleast 3, there spurs get larger with age.

Yes, but spur length is also determined by genetics and breed. Mediterranean breeds often get spurs that are larger sooner while slower growing breeds such as Cochins may not get a spur length larger than .5 inches until they are three years old.


You cannot base age on a spur size only.

No, just some pea combed breed in him. Could be brahma or anyh of a number of other breeds.

Then shouldn't he have a walnut comb? (assuming both parents are pure for their comb gene

)

Most egg colour genes are autosomal, meaning that each parent contributes equally. Of course one can only guess about the egg colour genes contributed by the rooster

My sweetest roos have always been the ones with the longest, fastest growing spurs. No idea why. DandeLyon's were nearly 3" long the last time I removed them. He is a sweetheart.

a friend did a little research... and if i understand it right.. both parents contribute to egg color.. what you get is based on the dominance of the color though...
blue/green is actually dominant.. but sorts co-dominant.. in that something can put a wash over it.. how you end up w/ olive eggers mixinf a green egger with a dark brown egger....
i have an EE roo.. don't know what color egg he came out of because he was a feed store baby... i now have 3 week old offspring from him and my leghorn.. i'm hoping when they get big enough to lay it will tell me the color the roo is throwing... depending on how the white works it will either be the true color the roo is putting in, or a lighter version of it...
but the good thing is, if it hatches from a green egg it will either lay greenish eggs or pass that green onto it's offspring...

granted... this is all just if i'm understanding it correctly from what i've been told.. if i'm wrong and someone knows better info please let us know...

Not co-dominant; your use of it is similar to saying that having feathered legs and having white legs is co-dominant.

Two separate things: 1) blue vs white eggshell and
2) coatings applied on the surface of the eggshell.

One gene, O or o+, determines whether the eggshell is blue or white. Blue is dominant. The material the shell is made from is either blue or white.

Many genes determine whether or not coatings are applied, and the colour. From these genes you can get lightly tinted ivory coloured eggs, stark white eggs, terra cotta coloured eggs, dark chocolate brown eggs, etc. A brown coating over a white eggshell is brown, the shade depending on the particular genes. Apply that same coating over a blue eggshell and you get some shade of green.

See, I was assuming just the opposite. I was assuming the pea comb was hetero. The pea comb does not appear to be "complete" and looks to be overly enlarged due to a single comb. But it's possible rosecomb??

hhmmm that's cool... that explains a little better what he was saying about washes.... i think....
so like my EE's green eggs are a gorgeous green on the outside, and a stark white on the inside.. does that mean it's a white egg with a green wash? does that give us a better understanding of the genes of the hens parents??

sorry for hijacking the thread... i'll move it to PM's if SS doesn't mind.. but this is good info for other people too....
one of these days i'll get a good grasp on all this... ssoo many variable in there though.. lol...
