Pens, are those a bantam breed? Never heard of them before.
Considered medium sized. They are supposed to be rare. More of a rounded body type shorter legged breed. Dates back to the 13 century. So far I'm liking them. These are their first eggs. They'll be breakfast for me. Eggs are medium when older. I got them in hopes of having a breed that would do well free ranging. But if they fly too well I'm not sure that will work out. Greenfirefarms has them. I got eggs off eBay and had a good hatch rate from them.
