Lavender Ameraucana Breeders .... UNITE

[Rorporp23]

Has anyone ever split to white? Or will the genes in that combo hide too many traits (coloring like an EE)

I didn't intentional but my Lavs are throwing whites in my second generation. The white shows OVER the Lavs. They hatch gray and yellow.... eventually turn all white. The lavender will not show with 2 copies of recessive white.

I personally would not make lavenders from whites. Black are your best bet with the lavenders. I did make whites from my lavs LOL. Pretty ones too

Thanks - I am going to house lavenders with whites but wasn't sure how breeding would go. I just won't hatch from my whites!

I have done it before and have some bantam in lock down now.My whites are based on black and the splits are black.

O.K. Lets look at the Mendelian Model. Symbols I use.

B. for Black controlled by one gene in a pure form Pure recessive since all colors are made up of black genes modified in one way or another.
Br. For Brown which is a black modified by a dilute modifier which is an incomplete modifier as is the black modifier which has resulted in Grey. One has the ability to completely modify black to blue or when in consonances with with another modifier to Lavender . That is the modifier which expresses the Br. Gene has been altered to modify the black to red.

White is expressed as as a Color and also as the pure dilute in either W which is for the color white and the mm which is absence of a color to modify. This gene is expressed as an albino chicken in its purest form. The blue eyes and no coloration to the skin and eyes.

. Place the colors you desire to work with in this model and you will find that in eight cases only one will be a pure mm. I hope . It has been a while.

Is this model based on chicken genetics or other animal genetics?

I am just learning chicken genetics, and from what I understand in chickens a black chicken is not controlled by one gene in a pure form. A pure black chicken requires at least two separate genes to express as black. Even E (Extended Black base) requires another gene to modify the whole chicken to a black bird. And E is a dominant gene - not a recessive gene..

I am not sure how your Model will work in chickens.... Or if it does it doesn't mesh with any other model of feather coloring that I have ever seen.

What is your Mendelian Model based on? Or is it describing each separate feather's possible coloring? I would like to know how to apply this to feather coloring - but I don't know where to use what you are describing...

If this is still based on the question of crossing to a white am..... they can be either Dom White (unusual for ams) or Recessive white. If you cross a recessive white to a Lav (basically a black chick with the lav diluter) you will get black chicks split to white and lav both will act independent of the other. If you breed those chicks back to Lavender you will have the Lav gene to express in the next generation. If you breed those first chicks to a White you will have the White express. If you breed those first chicks to each other (not a good idea) you will get some express white, some express lav some express both Lav and White (white will probably be what you see visually....my chicks are usually white) some will be splits for either white or lav and some will be just black.

You can always try the chicken calculator if you want to play with colors.

OH BTW if they are dom white all the chicks will be white with some black leakage.

One of my 7 chicks from my lavender/split hatch is acting sick. They are only a week old. The sickly one still eats, but she is smaller and does not run around the way the others do. Her breathing looks labored, and she just stands around. They are on medicated feed.
Do you think my rooster who suddenly dropped dead passed on some kind of unhealthy genes, or does this just happen sometimes? I have lost chicks before, but usually they were shipped hatchery chicks. I have only lost a chick that I hatched in the incubator once. At least the others are looking healthy so far.

 

[Goose and Fig]

It could just be failure to thrive. It happens even with the heartiest birds chicks sometimes.

Still- keep an eye on the others- I am already hearing of people losing chicks to cocci this season. It usually strikes my brooders around June, so I am trying to get all the hatching out of the way before it gets ungodly hot.

Thanks. I'm glad to know this just happens sometimes.

I need to know more about cocci, though, because today, I noticed another chick (different breed, same hatch), looking sluggish and not eating much. It could be paranoia, but it has me worried. I have them on medicated feed. Is that sometimes not enough? I have not seen any bloody stool, but they are on shavings and constantly digging.
