Lavender x Buff = Black?

[bantamhart]

Hi Everybody. As you can see above. We've recently had chicks. I have had eggs under my hens from a lavender hen and a lavender cockerel. Along with eggs from a lavender cockerel and a buff hen. However, somehow, we've managed to get one black chick. Can anyone explain this?
Do you think she will stay black ? I own all of the parents to these chicks, so i know there is no way possible black could have bred into my flock, as i don't have a black birds lol! Unless there is some cockerel sneaking into my coop at night.
To add to all of this, we've had chicks from our buff x lavender, and they have turned out half and half in color. Confused.com... D:
HELP! xD

Your lavender birds are really black birds with 2 copies of the lavender gene. If they were lavender splits (one copy of lavender) they would look black.

I agree with what you're saying...I did the same breeding this spring. But how did Bantamhart get 1/2&1/2 chicks? Could there be blue in there somewhere?

Buff is complicated. In playing with the chicken calculator lavender x buff gives solid black. So I guess it depends on what genes the buff carries. I am sure one of the genetics experts, such as tadkerson, henk69, Sonoran Silkies, or Icelandic, could provide a better explanation.

you left me out of that Lot... But I help him out..


as previously said, Lavender is actually a solid black bird that is modified by the recessive gene lavender, Buff genotype is complicated but is well known at this moment..

so lets try it..

Lavender genome is
E/E = Extended Black in Homozygous form
S/S = Most are Silver Based but they can also be gold based(hiden by extended black)
lav/lav = Recessive lavender, one copy cant express lavender, you need two...
co+/co+ = wildtype non columbian restricted,

Buff genome is

eWh/eWh = most Self Buff Birds(completely orange no black shown) are Wheaten because of all of the allele this is the least to express black pigment which is bad for a self red/orange/buff/cream birds

s+/s+ = they are gold, they would be self white if there were Silver based(food for thought, I bet you didnt know that)

Lav+/Lav+ = wildtype non-lavender Black/
Co/Co = Columbian Restrictor, dominant, very little effect on Extended black , but it may have some on heterozygous Extended black like

Buffs have other Powerfull restrictors, maybe Db and Mahogany combined with Dilute and other red diluters...


so What would a cross of them look like?

E/eWh = Extended Black Heterozygous, chicks will hatch solid black with cream underbelly
S/s+ = if they are S/s+ the males will have yellow/lemon hackles, breasts, if they are s+/s+ the color will be orange instead
Co/co+ = this will allow for some ground color(yellow or orange/red) on the hackle saddle and breast of the adult birds
Lav+/lav = this will not allow for lavender to be express as it needs two lav genes

Nicalandia, thank you for the lesson. I'm sure you've been over this all before and I appreciate you taking the time to post.

My Lav/Lav chicks seem to have something else going on...white primaries. Maybe it's just very light lavender color but I didn't see this in the parent birds.

Bantamhart, can you post pics of the half and half birds....I'd love to see them.

White primaries as Adults or as chicks?

I wouldn't forget to include you but my spell check believed I meant Icelandic and I missed the change. Spell check makes more mistakes than I do I think.

thats a separate gene, I have had that out of my buff cochin outcrosses, it goes away when adults, what gene is that? I am clueless..
