The Legbar Thread!

[TwoBit]

Youweren't being rude... Punett created this breed and several others he was quite a genetics wizard...in the UK. We all had to start somewhere. Welcome to chickens! I hope you enjoy learning about them here.

If you remember studying Mendel and peas and the Punnett square in science class, that's the same Punnett.

Sorry I didn't mean to sound rude, im just saying from my point of view, I just liked the look of them so got them, I subscribed to this thread because I thought I might learn something about the breed that would help me, I don't want to show them, im not bothered if there not perfect, I just love them

Hi graciesmum---

I think everyone likes your turn of phrase. Punnett invented Cream Legbars, he was at Cambridge University in the 1930's. Seems between WW I and WW II - feed was scarce -- so knowing which chick would grow up to give eggs made it more economical for people to have birds and spend their scant resources on the birds that would provide return for more than just 1-meal of stewed chicken. :O).

We want to be sure that all the good qualities that Punnett put in the Cream Legbars are maintained by the people who want to breed them going forward...and that's what we are all going on about.

Ok lol, I understand that some people are avid breeders and are passionate about what they are doing, I didn't study any of that when I did science at school, would that of been economical science as I didn't do that???, I just was hoping to learn about the characters of the breed and any hits or tips to give them the best, so they can flourish, like I say I just like the breed and the blue eggs lol

The blue eggs are awesome! When we study basic genetics and probability in middle/high school, we learn about the Punnett square. It's a simple pattern to determine the chance of getting a genetic feature. ie. (note I am not a scientist, so these are not the correct phenotypes lol).

If blue eyes is recessive bb, and Brown eyes are dominant BB:

Say one parent has two copies of dominant Brown eyes (BB) and the other parent has two copies of recessive Blue eyes (bb),the square would look like this:
B B
b Bb Bb
b Bb Bb
So according to the square all children should have brown eyes but carry a copy of Blue.

Now say you have two parents with brown eyes, but who both carry a copy of blue (Bb).

B b
B BB Bb
b Bb bb

So you should have a 25% chance of Brown eyed children (2 copies of brown), a 50% chance of brown eyed children who carried a copy of blue, and a 25% chance of blue eyed children (2 copies of blue).

The dirty little secret no one tells you in school is that it quickly gets complicated -- some genes interact with others, some are "incompletely dominant", and there are a whole lot of genes we haven't figured out yet. :-/

would there be any interest in Cream Legbar Eggs from Reputable breeders in UK sent to USA

I am considering setting up an export scheme from what I know so far this is the rules

Punnet actually started off researching and documented Mimic Butterflies

Chickens was actually an afterthought as he was gifted some birds

 

[GaryDean26]

Buff Leghorns have their very own Pheomelanin Diluter called Di for Dilute, its a Dominant gene I am trying to Isolate right now from my Buff Cochin line,

[GD26] Perfect the Di is exactly what it was hoping some one could confirm. He descried the dilute hen with alight pink breast and the others pullets as full salmon breasts. He selected for the full salmon breasted in his project.

... nothing on Dr. Punnett's paper indicate the Chilean cross x Buff leghorn cross birds made it to the CCL parent stock.

[GD26] No, the "Cream Plumage" paper doesn't indicate that the Chilean cross x Buff Leghorn crossed made it t the CCL parent stock, but the article on the creation of the Cream Legbar by Michael Pease in the 1948 annual publication of the Auto-sexing Poultry Association of Great Britain does.

Clarence Elliot started back to England with his exotic blue egg laying hens from Chile in 1927. The work on the Gold Legbar was not started until 1935 and Michael Pease didn't discover the Cream Gene in the Legbar Project until 1941.

The "Cream Legbar Legend" is that a cream colored Chilean Hens from Elliot were used in the creation of the Cream Legbar, but the Chilean hens would have been more than 15 years old at the time if used to create the Cream Legbar. It makes a nice story for selling blue eggs at the posh market stores in the UK, but the truth is that the Buff Leghorn crosses with the off F2 offspring from the yellow Chilean Hen and Silver Penciled Hamburg were used to create a cream based brown Leghorn type birds that were non-barred, crested, and laid blue eggs. They are was were used to create the parent stock of the Cream Legbars.

Thanks for the pics, I believe the difference we see on the hens is the different Barring gene at work

[GD26] Thanks.
