Color Breeds

[Swilso3]

If you breed a pure bred Lavender Orpington Roo to a pure bred bar rock what color will you get?

According to this you should have sex links. Black female chicks and barred male chicks.

Lavender is a recessive gene that modifies a black feather to look that grayish lavender color. Since it is recessive it will have no effect on the chicks' color from that cross. Since the rooster is pure lavender the genetics are solid black underneath.

Barred Rock are also black. The barring is a sex linked gene. So the chicks will be black when they hatch. No sign of lavender. Since it is the hen that is the Barred Rock in that cross, the chicks will be black sex links. The boys will have a spot on their head, the girls will not. When they feather out the boys will be black barred. When they feather out the girls will be solid black.

If you breed the pullets from that cross back to their father about half those chicks will be lavender, half will be black. They will all be solid, no barring. They will not be sex links.

If you breed a cockerel from that cross to a pullet from that cross you should get about 1/8 of the chicks solid lavender, about 1/8 lavender barred, about 3/8 solid black, and about 3/8 black barred. They will not be sex links.

Thank You! Its so interesting. Where do you find this information? I also have Buffs and EE for my Lavender Roos

A lot of it was reading on this forum and following links. Playing with this calculator helped a lot too.

In theory a Lavender roo over a buff hen will give you a solid black chicken. It usually does not work that way. You still get a chicken that is based on black but some of the genetics in buff cause you to get some yellow or orange feathers. This might be individual feathers, it might be in blotches. I think you can get some really pretty chickens with that cross. If you try it, please post some photos in this thread. I like to see how those turn out as chicks and when they feather out.

An EE doesn't mean anything when it comes to feather color or pattern. EE's are not a breed, there are no rules. You might get a lot of black chicks but then you might get about anything.

That is Sooo fascinating!!!

I've been on that kippen site a lot and I just can't figure out how to use it properly. Also it doesn't have all the colour options of my flock, or at least I am not attributing them properly out of my own ignorance.

That is the problem. What genetics do you actually have to start with? There are different genetic ways to make white, black, buff, or about anything else. You don't always know if you are looking at blue or lavender unless you have experience, for example. Some genes are dominant, some are recessive, some are partially dominant, some only act if other certain genes are present. There are a lot of modifiers than can give you some really weird effects, like diluters that can change block to yellow or orange. But they only turn some feathers yellow or orange, not all. I think you hit the problem right on the head. What do you have to start with.

But that calculator can give you some basics of how it is supposed to work. It is a useful tool in understanding the theory but in practice you may need additional help.

Im hearing chirps from the eggs so we will see what I get with the EE and buff hens i bred him to. The others are with purebred Lavender hens. I will post pics! Thank you again
