As I understand the white sport it is simply a recessive white gene.

To me that makes sense. I did not get any white sports last year. Last year was the first year I bred my birds. I had 2 hens and a rooster. This year I kept 7 hens (one original and 6 babies). and one rooster.


One of my original three had the recessive gene. In 25% of his/her offspring would have the gene, in a recessive position.

This year I have 2 birds with recessive genes breeding, Giving me 25% of their offspring as white sports.

I assume it is mother/son , but I could be wrong. if the rooster had the white sport gene 2 of my young would have the gene as a recessive, I am not getting the whites on a high enough number this year for that to be the case.

If you take 7 birds and one egg a day, in the perfect world,. that is 28 eggs a week. I set once a week, I get one white a week basically so only one hen is giving me the egg with a white in it. I have my birds separated into 2 groups in hopes of figuring out who gives it to me. I now mark the eggs group 1 or 2.


Of course, if I am right and my mother/son pair give me the whites I will get more next year as the offspring of theirs will have the recessive gene.

And if you're right it is several genes, I am screwed and have no idea what is happening..LOL

There are so many reasons for a white sports and white birds in general good luck. They are pretty though. I know someone with a white cockerel near here. She says if paired with a normal bird the offspring should look rather normal. Seems to indicate that they wont breed true like the article says but who knows

I know turkey genetics better than chicken genetics,

That said, I know chickens have a more complicated color determining system. So I am flying by the seat of my pants here.

I think the blog person will be surprised in F3. I would not expect the whites to only breed true if crossed with another white, and I think this will only be the case in CLB's and not other breeds where whites pop up.

The difference being the close genetic similarity between all of the CLB's in America. We do not have a large amount of genetic diversity at this point. Now I expect some people will add in another breed to try and get a foot up on color, body size or something by adding in a different breed now and then and then diluting the "effect" in future generations until they have a bird so close to a pure CLB but with the "new" trait enhancing it.

Yeah, I know it is hard to believe some people would do this for a ribbon.

To me, the number of whites I get and the fact they did not show up until f2 leads me to think mine are coming from a single gene. If that is the case I should be able to breed them true.

I thought there were others breeding white sports and breeding them true at this time. but again I could be wrong. The adult pictures I have seen of the whites are beautiful. I Would really like to start a line if not for anyone else for my own use. I have even been a tad stingy with my eggs that others want this year because of the white gene. (I am just a selfish SOB I guess,,,

I plan to hatch every CLB egg I get this year until I get 20 whites. Then I will make them a closed flock. I have promised a white rooster to a fellow BYC that works with bird genetics and is a breeding genius. I would love to see what he can do with them.


Heck, maybe we can even get a SOP for whites! That is dreaming I know.

I appreciate your wishing me luck on them, and if you have any ideas please let me know what I can do to check or make this work better. I only have 3 chicks that lived of the 5 I had hatch this year (whites that is). The first had a defect and the yolk/stomach was outside the body. I thought that might be a inbred problem. The second was trampled in a stampede of CLBs. (Murphy's law) I now treat the whites with kid gloves. I am hoping for eggs I can hatch in August so I get 2 generations this year..


Time will tell. It is fun for me, whether my science is off or not to have a "breeding project" that is different than the normal ones of keeping the lines pure.


I have even started working on getting a BA with a rose comb. I know it will no longer be a BA, but here in Minnesota the single combs do not do well in the winter.

Another story for another thread..

Thanks again for the wish of good luck!

Good luck with your plan -- there is a thread someplace devoted strictly to white recessives:

https://www.backyardchickens.com/t/827877/white-sport-cream-legbars

don't know how active it is ETA- perhaps some resources, contacts or answers there for you.

- and there is one that was eying SOP for whites:

https://www.backyardchickens.com/t/...-not-breeding-to-the-proposed-cream-standards

Not trying to rain on anyone's parade, but I maintain that a solid white CL wouldn't be autosexable..... and it is surprising that there aren't larger flocks of or presence of the whites?

ETA - I'm also not sure that the same understanding of 'breeds true' is shared by all. Some think that birds with a white recessive gene set could be a parent, my understanding is that the offspring must replicate the parent.

While I think having standards is important breeding birds you love is very important as well.

anyone having troublesome cockerels? Mine was hatched out in July last year so he's now 9 months old. He was hatched in an incubator but raised by a broody. He's started behaving more an more aggressively towards me when I try and "herd" th flock (him and 4 hens) back into their coop, to the point where if I try and "shoo" him in a directions he will jump/attack my foot... Not sure how to handle it, he's always been fine up until a week or so ago. If I crouch down with treats he's still happy to come and eat corn from my hand with the hens (not pecking me or anything just feeding happily). Can I try to correct his behaviour or shall I just get rid of him? Thanks

Maybe important but I'm not sure: I've been at uni for most of the past 5-6 months and only returned over the weekend, so it could just be me he's aggressive towards and not my family who he sees/interacts with more regularly?

I've been home most weekends and over Christmas

That's a possibility. It is tough when one that was sweet no longer IS -- and maybe since you are less familiar he does think when you advance that he needs to protect his hens. --

I have one that is now 4-years old and when he got aggressive, I got a spray bottle -- and set in on the thinnest stream - not the soft spray. I used it to herd him for the longest time -- and if I thought he was thinking about attacking I would either squirt the air, or squirt toward his feet. If he was purely defiant, then I would shoot water right in his face until he backed down. -- Now he is with a female as a breeding pair in an Eglu classic, so he doesn't have the opportunity to come up behind me and generally I fill the feeder before I open the door in the morning.

Hope that you will find an answer - but maybe he has lost your trust -- and hopefully there are no little children that he could see as a threat to his hens -- and go after the kids.

Ive read a bunch about aggressive boys and it seems there is a hormonal shift (aside from spring time) after about 2 years old where even the sweet ones develop an aggressive streak. Just seems to be part of their maturation cycle. There are lots of other factors that are important but time with the birds daily is one of the most. Long absences will allow them to forget who you are (actually doesnt take all that long)
