Rumpless Game With Tail! What!?

[Brandon97]

Hey its brandon
I have recently aquired 12 bantam chicks(pullets and cockerels 6 wk olds), and the rumpless game i had has a tail! (almost a sebright hen style tail)!!!
Is it not pure bred, if so what is it crossed with, it has every detail of a rumpless except it has a tail!
Is it genes?
Here she is:

ANY IDEAS WOULD BE HELPFUL!
I WANT TO BREED HER, SO I NEED TO KNOW WHETHER TO BREED HER WITH A RUMPLESS FOR PURE BREDS, OR WITH MY BARNYARD SELECTION BREEDING COOP!

thanks in advance

I have never heard of a rumpless game but in Araucana's, they sometimes produce tailed and partially tailed chicks. There isn't an off/on switch for tails. It has to do with how short the back is and it can vary from way too short (no tail and back looks chopped off too short) to full tails because the back is longer.

In Europe they have a bird that looks like a rumpless OEGB
