This picture is from websurfing so it's not mine but I "think" I see three spurs on this bird. Besides the Sumatra what other breed with throw out spurs like this.
Genetic gurus welcome.
One leg has two spurs coming up and the other has 3. Had never seen anything like this before him. Had planned in keeping him for breeding and was just out looking at him last week and realized his spurs looked odd. Unfortunately this is what I discovered.
Well I have to figure the tendency to develop these extra spurs would be inheritable and although it's interesting, it's not something I would want to have in my stock. At least with some breeds that you mentioned at the beginning of this thread, it is known to occur from time to time so it may be accepted in breeding stock. I don't know that for sure in these other breeds but with Swedish flower hens, this is apparently very unusual.
