Link between comb type & feathering up?

Postby sewren » Thu Oct 29, 2015 11:57 am

Random question, but does anyone know if there is a genetic link between comb type and speed of feathering? I ask because I have 4 chicks that are mostly SLW but with a bit of orpington (1/8th, I think) and one of them popped out with a straight comb, and that chick is feathering up noticeably slower than the rest of them - he's 6 weeks old and still has a lot of bare patches and pin feathers showing. I think 2 of the others are also boys so I don't think it's a gender difference.

Any ideas, or is it just random chance...?

According to http://www.edelras.nl/chickengenetics/linkages.html:

  • Slow feathering is on the Z-chromosome (sex-linked)
  • Rose comb is on chromosome 7
  • (And for random interest) Pea comb is on chromosome 1

So, as far as I understand the subject, no genetic linkage between them (requires them to be on the same chromosome, and degree of linkage would depend on the distance they are apart on that chromosome).

Oh well, guess it's just random then that he got all the dud genes - ha ha! Out of interest, all of the GLW and blue laced reds have feather up much quicker than all of the ones with the orp cross dad - he's just even slower than the rest of them, poor wee lad!

Great resource that website though (and now I'm off to google some of the other traits in the table - 'lady killer' and 'fishy taint', in particular! :? )
