They are a dual purpose breed. Standard weights [British Standard] is cock 7lbs & hen 6lbs. They are reported to be good layers of tinted eggs & the hens are reported to be dependable broodies.
My ancestry is Scots so these have long been an interest of mine. This is the first year I noticed them in the Sand Hill catalog. I ordered them & just received notice of my expected shipping date. I'm pretty excited about getting these birds.
BTW-Sand Hill has them in Cuckoo only.
I don't live far from Cooperstown. Would love to see your birds sometime, or maybe you are showing in the area? Are you getting the Scotts Grey also? My family is also from Scotland.
Happy Country Hens
