I'm still trying to get my head around all the gene stuff. Both E (extended black) and ER (birchen) are not very sexually dimorphic. I don't get how the Black Copper chick down is black and yellow which suggests E allele based yet, apparently they are ER based when done correctly which means they should be born black (no yellow/white down.) Must have to do with all the modifiers that have to be present for Black Copper. I'm still reading!!!

I don't believe anything about black coppers (aka. brown-reds) is sex-linkable but barring definitely is. Only one copy of B (barring) in the female because of the chromosome it resides on. Barring, btw, should be modifying the E allele when done correctly in Cuckoo Marans although perhaps that is not the case with Golden Cuckoos?

Like I said, still reading!!

Amended to add: Apparently the Silver Cuckoo Marans should be based on the ER allele as well. Back to my reading ...

Attempted to amend my last post. Doesn't show up as amended for me until I reply to it.

THe basics of black sexlink is that one parent must be homozygous for black and the hen must be barred. So if the hen is barred and EE, like barred Holland or BR or cuckoo marans, the rooster can be a number of things, just not white and not barred. (My understanding so far) If the marans is birchen based this should work! Tad Adkerson's thread lists Brown Red Ameraucanas as Birchen (E^R/E^R). BCM are the same, I think. At least to my novice eye they do! LOL THanks for helping me think it through.

Ok I don't know any genetics, but I do know about sex links some.... I asked on the EE thread and Illia told me that my Columbian type EE Roo x my BR pullets would make great Sex links. He is mostly white, BUT in saying that he is NOT ALL WHITE and I could see that could cause a problem seeing the spot from barring. I had one chick from my first hatch and he as grown into a nice White with some red on his wings and you can just barely see the barring on his hackles and I never saw that spot at hatch.

I have heard that FBCM x barred anything will make sexlinks.

Stoo~ Don't know anything about the sexlink thing unless it is being crossed with a barred bird. If the black copper is being crossed with a barred then yes they will be sexlinked but if you are referring to a Sexlink chicken...I haven't got a clue.

Barb~ What are you confused about? Is it how the E^R / E^R and E/E are written? Some use E^R and some use ER..is that it?

Got it. Thanks Donna. Gotta give the extra boys a job.

Donna~ I am very sad to hear of the little BCM not doing well. I don't what it would be....all 3 of the little BCM that I just hatched out that had short down are doing fine. I'm sure you have...but do you have them on a vitamin water or something?

Hey Kim...how did your last hatch end up going?
