Great pix. :thumbsup Yes a fantail, but can be mixed with other pigeon breed. Not of a concern, since you just want pretty pigeon pets.
I still think you may have 2 males by your description of behavior:idunno

I suspect you have 2 males. I also see that the pigeons are not same breed.
The second pix pigeon looks to me like a Pouter.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,,,,,, :highfive:
