Well, that's an interesting question.
I have done them for about 2 years but feel as though I've done them forever. Mr. Beauford was talking me into them, helping me breed them, etc. long before I actually bought them...I got my birds to prove to him that not everyone could do well with the birds and not everyone would fall in love with them. I got the birds for fairly cheap because he wanted to prove me wrong.
The first cockerel died, which was a blessing since he was being dreadful to work with, but the second cockerel, Clyde, was and is amazing. I fell in love with the large size, the gentle ways, the ridiculous antics...darn him. Forrest knew I'd fall for them, but I REALLY wanted to prove to him that not everyone could do them and not everyone loved them.
I doubt that I could ever keep the birds in "mint" condition with those tails. My Minorca...absolutely not unless he were on shavings 24/7. It just seems odd to me that he's able to keep the birds in a rabbit hutch and not have tails that are shred to bits!
I know sumatras though...good Lord. You could do almost anything to those tails and wind up with perfect sickle feathers....
