question about Barbado sheep

I have an opportunity to buy up to 15 ewes of this breed. Most are pregnant, so I'm not fully sure if I am ready to help with lambing yet, but anyway. The price is $40 each. I want them to raise for the dinner table. $40 seems pretty cheap, do you think there might be a problem with buying them?

I copied and pasted some information on the breed below: (found at http://www.ansi.okstate.edu/breeds/sheep/barbado/)

"The Barbado breed originated in Texas. The breed originated from Barbados Blackbelly sheep which were crossed with Rambouillet and mouflon. One of the uses of the Barbado is as a trophy animal on game ranches due to its large curled horns. It is typically tan, tan with a pale or black belly or pied. The coat varies from short hair to coarse wool with a large amount of kemp fibers. Males show the horns for which the breed was selected and the females are polled."
