Its a great subject.. And its too bad so many breeds are close to being lost. It was like this with antique apple varieties. A few trees were saved out of many thousands. Left to go by the wayside for the more commercial varieties that are good keepers and shipe well..but if you have ever had a good chenago strawberry apple or yellow transparent in apple sauce, boy what a treat. There were pink fleshed apples that were favored for apple sauces now only a couple varieties. One of my favorites now pretty much lost to time was a cream apple, very smooth texture creamy like the name says for a taste treat apple sauce. pretty sure its gone now. the one tree we knew of was struck by lightning and no one thought about propegating it at the time, it came with a farm that was built in the early 1800s.
Sometimes we give up the better tasting birds for more meat or more eggs. I would love to see people take more interest in these rare breeds, but finding them is a real challenge.
More and more fine resturants are asking for the Poulet de Bresse.chicken but only a handful of breeders have them and they dont sell hatching eggs or chickens. very hard to find birds.
A freind from california said she saw them once at a show but they were under lock and key.
