Blackcock
a name for the male of the black grouse or black game, called also the heathcock (tetrao tetrix). The female is called the gray hen, and the young are poults. The blackcock, as its name imports, is black, having, however, white on the wing covets and under the tail, the two forks of which are directed outward. It is about as large as a domestic fowl. It is found in some abundance in Scotland and less plentifully in England. The eggs are from 6 to 10 in number, of yellowish gray color, blotched with reddish brown. a
