This has been a strange one, never had one look like this guy, or ever make such a drastic late change.

I had been considering putting him over some splash blue columbian hens (splash blue lights). At least when he was looking more like a red columbian. Now not sure what to make of him.

All my other cockerels in these projects have historically had either single laced breasts, or the solid dark breast of double laced, or partridge patterns. Other than when columbian had recently been brought in to improve something with the project, resulting in poor partial lacing, which is not the case with the red birds.

I have limited experience with colors/patterns outside of those mentioned. I would appreciate any ideas/experience here.

I have also limited experience with those colours , but change from red to black breast says to me, that your cockerel might have been somehow hormonally challenged before. Just a quess.

My first thought when I saw him - still a young boy, and young laced stock go through dramatic changes as they mature.

I don't know if Db is involved in your bird. Mh - Mahogany might do similar strange things?

If you start getting bleached out (silvery) chick downs, then you can start suspecting Db (or Di). Co (particularly with Ml -eumelanisers) should add eumelanin to the chick down, particularly the back. And Co/Co tend to be darker downed than Co/co+. So the chick down might give some clues.

--------------------
As to Db - Dark Brown. It is very similar to Co in that you can have eumelanisation of neck hackles - just add heaps of eumelanisers.
Eg, this following rooster went through some similar changes as a youngster (particularly on the breast):




One of the most tested roosters I possessed, so I know the following as accurate:

His genotype:
e+/e+, Bl/bl+, Db/db+, co+/?, Lav+/lav, Mo+/mo, Pg/? plus eumelanisers.

p.s. -his parents were Black Mottled father and solid Blue mother (dark blue). So Db can hide in solid eumelanin birds, including with het. E/e+ or ER/e+.

When I crossed a closely inbred sister (with e+/e+ and Db like chick down) back to this blue boy, I got some unusual results in the sons (hens were drab brown though - not pretty).

Eg:


------------------
The following boy is a much later generation, distantly related, with wheaten in there too:
As a youngster:

Older...

-definitely co+/co+ (cream chick down, not buff), but don't know about Db, & was a red enhancer introduced too. Something was putting partial phaeomelanin on the breast.

p.s. - I never once got a solid phaeomelanin neck in these d'Uccles segregating Db. They went from columbian striped right through nearly solid eumelanin (including ER/e+ or E/e+ ones). Always eumelanisers in the mix.
