Garden Hens in Cheshire, from whom I've bought hens in the past, are ending their rare breed chicken business. I noticed on their website today that they are asking if anyone might be interested in taking it over. They may also be selling breeding groups for anyone interested in rare breed conservation.
I don't know anything about the business or breeding side of it myself, but the Vorwerks and Barnevelders I bought from them a few years ago were really nice-looking, healthy, strong birds - who laid as well as Jackie, the owner, had said they would - i.e. not egg-machines but useful.
I know Vorwerks in particular can be hard to come by. I loved having them - beautiful birds and very alert and curious.
Just thought I'd post this in case the right person just happens to be around here someplace.Link to their site below:
