I need some Lavender genetics help!!!!!!!!

[robnms]

I had a pair of Lav Orps in a pen with my Coronation Sussex Splits and did a test hatch with three of the eggs and all 3 hatched. I have one pure lavender chick and two that are black with some reddish brown on the head and was wondering why? They also all have dark slate feet like the lav roo. Here's some pics, sorry they're not the best.

I just know that lavender is recessive...

argh, stupid thing keeps messing up.

See previous poster.

I would think that the black ones would be the Light Sussex's chicks. Lavender x Light Sussex = Coronation Sussex looking birds once this offspring is mated.

As far as the pure Lavender, are you sure that you didn't set an egg from the wrong pen, or something?

I had a lavender Ameraucana/coronation sussex hatch. It looks just like the other lav Ameraucanas, I cant even tell which one it is anymore.

No, Lavender x Light Sussex does not = Coronation Sussex. To have ANY lavender, both parents must have the Lavender gene.

I mean Lav x LS equals coronation sussex LOOKING birds, not true sussex. This takes a few generations. Is that what you mean?

As far as both parents having to have the Lavender gene, yes, I know.

ETA: Oh, the coronation will be all pullet's. The males will not be coronation-looking like pullets. For that you must cross back to a Light Sussex roo.

The black chicks with the red faces are not unusual. I have hatched a large number of chicks that look similar to yours but mine carry birchen at the E locus. Your chicks are black because the lavender male is actually black and the two lavender genes have diluted his color to the gray or lavender color.

It is my opinion (an hypothesis I am working on) that the red in the face is due to a restrictor. The chicks as adults should be black and may leak white or red- the amount depends on the restrictor or restrictors carried by the bird. The black shanks and feet indicate the birds carry the extended black allele.


Here are a few that I have produced. They are birchen or birchen/wheaten heterozygotes and not extended black like your chick. They also have a restrictor in them that changes the down from black to the dark brown color.

This is a white bellied version.
