My understanding is there are very few of us working on them. I now of 5, including myself. There are a couple other folks on byc with them as well. Some of us have grouped up to share stock to continue improvement and increase fertility, so this breed is not lost. I had recently heard from someone who used to raise them that they lost their whole flock due to fertility issues and they could not reproduce to keep the line going.
This is so critical that we work together to keep this breed alive, which is one reason they are of serious interest to me. They may not be perfect examples, but we are working to improve them, both physical aspects and longevity. There is very little info on the net about them and with so few breeders, it is a challenge to get diverse genetics. I am hoping by working together we can all help each other to keep our lines going.
I have been fortunate that my birds maintain some excellent fertility yet, and will build up a bigger flock this year. In addition, I plan to bring in another rooster from a different 'strain' hopefully to make them more sustainable.
The breed itself is the most wonderful bantam bird I have raised. They are sweet, gentle little bantams and require very little space to raise. The roos do well together and and typically very family (flock) oriented. The hens are little chatter boxes and love to "talk" to you. Just beautiful creatures all the way around. They are not really good layers, which makes it so important to hatch what you can, when you can. They do have broody tendencies as well. They fly very well, but are not flighty birds unless spooked suddenly. Personally, I am not a bantam person, but these little ones are very special to me and I enjoy having them. With their historical value and the fact that they are near extinction, drives me to continue working on them and building their numbers to ensure we don't lose our US pyncheons.
