Fluffy Butt Acres: Stories of our flock

Yes. I may not have understood correctly but blue & white are the only *true* colours. Brown is an overlay on either white or blue. So genetically if you have a marker for blue & a marker for brown the blue would dominate & you would get blue eggs but if 2 brown markers line up you would get brown eggs ~ & that's assuming I have some grasp of my very limited biology classes.

The good news is you actually have coloured eggs & your naughty girls have *coloured them in*.

I think this is something we all agree on! And it is truly amazing how mu

It's like your internet dropped mid post Kris........

My gosh, you're right! They are naughty!

It is a relief and it isn't. The debate now rages do I need to do anything or was this all just fluky. They were all locked in the complex today except for 2 hours if free ranging in the evening. You would think with all that closeness someone would have irritated her.

I don't know Bob. I find the more run time my lot have the more trouble I have with them. If they have been confined they are so grateful to be out most of them behave. Aoife is generally the exception but she doesn't cause as much damage as some of the others.

So I'm giving them ro much free range time?

I didn't say that! I was commenting on my unruly lot.

No. Brown or tinted eggs happen when a dye called protoporphyrin is laid over the shell. Brown shells aren't brown inside & out. Blue & white eggs are. Have I made sense?

perfect sense to me...

Yes, but Kris said Blue and White were dominant genes.

yes and no, as the Blue or White and the Brown coating genetics are separate. Blue and white are the only shell colors, but the Blue gene can be either Dominant or recessive. Chickie Hawks daughters get the blue shell in about 50% of their population, and they all get the Brown from both him and their mother, so they lay varying shades of green or brown. (I’m wondering how it will go if I add Sapphire/Hyline reds to his pen? Hopefully we will see this winter or early spring +20 weeks!)

In some breeds like the CCL the blue shell gene is dominant, and is passed to all their offspring. But the blue or white shell gene is separate from the genes that go into putting the “brown” coating on. Brown on blue shells gives a green, and on white shells... some shade of brown. Anywhere from light tan to dark chocolate Marans colors. That’s why my breeder uses a CCL Rooster (Dominant Blue/Blue) over leghorn hens (White/white) to get my Sapphires as guaranteed blue Layers (Dominant Blue/white). If I cross my Sapphires to my Marans I get either tan, mint, olive or brown depending if the hen passes on her Blue gene or the white to her chicks. The brown coating genetic stuff I don’t fully get, but it seems to pass on as a dominant trait, at least in all my pairings. I don’t think you can breed a brown layer and a white layer and get white shells from their offspring.

edit to add: each chick gets two sets of the blue or white egg genes, one from each parent.

Hit the nail on the head! I went back and fixed it though...

I knew I wouldn't have it exactly right. I'm not much of a scientist & it all gets very confusing very quickly for me.

The last few posts has me screaming in my pillow! Very confusing!
