As far as I know, no one has ever proven the existence of dun in the Serama. I've asked about it before
here. I would love to be proven wrong. If you think you have dun, breed it to black and show that it produces black and duns. Then breed dun to dun and show that it produces khaki, dun and black. I know Seramas are very diverse genetically, but as we select and refine their colors, I think we will produce many true-breeding colors, including coco pop. It just takes a lot of time and hard work and good record-keeping.
but that's what i'm saying about dun or chocolate birds... it's super hard to breed out the other traits because if a serama is a patridge/columbian/melanized/dun/patterned/silver that means that it's split for wheaton/blue/choc/lav/duckwing/black tail/birchen/lemon/dilute/barred/mottled/recessive white and everything else possible...
LOL...
you guys see what you guys are trying to do...? i think it's great, but it's really going to be a group effort to get this done right... my friend jose has some "cocopop" birds, so i'll help him try to breed out the other genes...
I got this from one of Sidqrid post on SCNA about cocopop. I am currently doing F1 X F1 to see if I can isolate and eliminate some colors. So far I got 4 chicks and 5 fertile eggs, I am planning on hatching at least 40 chicks from 2 single mate pens. I wil up date on the chicks color in 2 months.
Gumbii, is this what you are looking for ???
Cocoapops can be partridge based, wheaten based or mixed partridge/wheaten since wheaten becomes dominant in expression when there is Ml (more black) present.
They can be gold, silver and rooster can be mixed gold/silver as well.
If you want a bird similar looking as Capt. Cocoapop the founding father, you need a silver bird with autosomal red, having the pattern gene which causes the chipmunk stripes and lots of autosomal red (non sex linked red so not gold).
You also need columbian and/or Db (black tailed gene) pure or impure and some Ml (melanotic) but the latter may be impure which causes less thick laces on the breast.
The 'double lace' seen as one black (or choc) outer lace, followed by a white 'lace' and then the red feather field is caused by too little autosomal red to 'fill' the feather with red. What causes the red not to spread equally over the white feather is unknown.
The yellowish chicks, or chicks without chipmunk stripes are pure wheaten ones. Since wheaten chick down 'hides' additional genes.
Later I found out you also need ig (inhibitor of gold) in order to clean up the rooster's hackle since autosomal red may stick on hackle as well.
Since ig is recessive you need to inbreed to get really white hackle in cocoapops. This counts for hens as well which look like pencilled gold based birds but have silver white hackle, with (eb) or without (eWh) shaft striping like silver duckwing hens.
The duckwing e-allele e+, doesn't work, since the hens may have a salmon breast next to pencilling. But for the roosters it doesn't matter only you need more columbians to push away black into lacings in roosters. This is theory, because I never used an e+ silver hen to make cocoapops.
The best cocoapops are the light chicks with faint stripes (impure eb/eWh) with smashing orange back stripes next to almost platinum white stripes.
Cocoapop is an impure colour, you will always have a bit difference between the birds. Because so many genes are impure and the accents differ, the colour segregates similar to blue (from pigeon grey till dull black).
Just pick out the ones you like and continue to breed, but: the best ones are not the best breeders. Actually you should practice two pen breeding of which the F1 is actually considered as an end product.
