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.
