I vote for Allegheny.

Dominecker refers to the Dominique breed of chickens, an old breed brought to North America from England. They have a rose comb, and are barred, but not the same as the Plymouth Barred Rock.

Origin of the name is uncertain. One reference I looked at says early use in England was Dominic.
