rumpless gene ? (Tim this means you)

I posted this on the breed, I do not know if they are in the USA, I just thought they where so cute. I would love to breed these, and do some playing with genetics. I am thinking I will have to find some EE bantams that are rumpless & cross with Chabo. There is also a JB that has a super long tail that drags.

I confirmed the rumpless chickens have no way to waterproof their feathers, so weather is a concern. I wonder if the feathers can be conditioned with an oil to help keep them healthy.

I did find there are still lines of OEG that are rumpless in USA also called Manx Rumpless, someone had a few on another forum.

Hi There!

I came upon your thread here and am wondering if I could get some help in this area too?
I have a hard time understanding all of the genetic and genome language still. I have chickens for fun and let them breed because I like to see color variations.

I have one flock, 35 girls and one very happy satisfied Roo which free range on five acres during the day. I encourage my girls to go broody and place eggs of my choosing under them. Had a different Roo last summer and didn't get any rumpless. Kept all of the girls though and one very nice son. This summer I seem to have a small run of rumpless type Ameraucana/EE babies. So far I have four or five. All my birds have tails. No tails missing in any of my birds for the last two years. I have only one young Roo ( I had his father last summer) who is out of a blue egg and of my girls fifteen lay blue eggs. I am trying to figure what the odds are of this happening and which hen or hens are contributing - the babies are all different colors. Or if this is coming only from the Roo's side. However, he does have his sisters in the flock. So is this coming out because of the free range line breeding?

If it is more than once is it accidental or do I have something else going on in the gene/genome/etc. pool?

Is it possible to keep this going and develop a flock of rumpless from what birds I have?

Confused and Intrigued all at the same time!! LOL!

If it is Genetic then the rumpless gene should be being passed...

So if you breed the rumpless to rumpless you should get rumpless, if you only have 1 gender of rumpless you will have to breed non-rumpless to rumpless and see what you get...

This site breaks down the 4 kinds and gives various traits they exhibit to help you determine if genetic which type, note on indeterminate what that means is even though it is a dominate gene you only get partial expression of the gene, think of it like this the indeterminate dominate genes build on each other versus the total expression of 1 strong gene (dominate) or no expression of 1 weak (recessive) gene... I have always used the term "compound" for what I now know is called indeterminate dominate as expression became stronger with more of the gene but was always present.

Hi, thanks for the new notes!
With that many rumpless offspring, it seems like we could rule out the "accidental" version?
And if it is the "recessive" version, I suppose the roo and several related hens would have to be carriers?
Someone more knowledgeable could jump in right about now...

I am still wondering which version of rumpless I have, thinking it is "recessive" by reading the characteristics. I just don't know what a roachback should look like. Either way, it hasn't slowed him down and he seems to be fertile based on the appearance of the hens eggs; not sure I want to hatch any...

If anyone knows what type of rumpless you have, would you mind posting picks?
I'll try to do the same.

Well, here are some pics of my fancy "Buttless Wonders" LOL!! A couple do not have feathers in the tail end and a few others have only two or three fluffy feathers and others have real short kind of shaved off tails. I am not sure yet which are girls and which boys.. Still wondering if this is coming just from the Roo or in combo with some of the hens. Of course, the babies are different colors so I am
assuming different hens. So is this coming primarily from the Roo? So far my other babies all have tails. Still have hens going broody though so I will let them keep hatching. Up to 22 hens with hatches now and they are still threatening to continue!! ROFL! What are the odds so many hens going broody?
Any imput or opinion on the babies below would be appreciated. My chickens do have tails... really..
Sorry about the way the pics are spread out. Wasn't real sure of what I was doing with the pics and uploading.
