personally, if the birds are healthy, I would put them together and see what you get. if they're winning shows, then the type must be pretty good.I have black Wyandotte bantams that I purchased in February. The male won Res. R.C.C.L. at the last show I went too. I would love to hatch eggs from them, however, I'm a little concerned about something. I have been told by multiple sources - at one point a judge - not to buy birds from the breeder I bought them from. I'm not exactly sure why, but I did have one of the Wyandottes that I bought from that person die immeadiately afterwards, and the hen I have left had vent gleet before I treated it. Of course I didn't know about this breeder when i bought the birds. I'm worried that if I hatch them, the chicks will have hatching defects, etc. What are the chances of this happening? Would it be better just to not hatch anything from them? I know nothing about what line they are from and if they are true blacks.
worst case, you get some odd color or physical defects, then you know what the answer is. best case, you breed a best in show.
never know till you try.
I picked up a partridge cochin this weekend. ok body condition, horrible scaly feet, questionable age, but fantastic type and markings. so once she's cleaned up and out of quarantine, we'll see what she produces. if I can get even 2 or 3 chicks with her type i'll be happy. markings i'm not too worried about. i'll be using her in my blue laced red cochin project.
