Rat × Chicken

Mammalian Hybrids

Sir, to leave things out of a book, merely because people tell you it will not be believed, is meanness.
Samuel Johnson

Note: Any claim that hybrids can actually be produced from this disparate and poorly documented cross would require confirmation from a specimen.

Old reports about rat-chicken hybrids have appeared in American newspapers. For example, the following notice about a rat-chicken hybrid appeared on the front page, column 5, of the April 15, 1881, issue of the Weekly Graphic, a newspaper published in Kirksville, Missouri (source):

    A Canton [Missouri] man recently caught a monstrosity that was a cross between a chicken and a rat—having the upper portions of the body, including the wings, of a chicken, and the lower portion, with hind legs and a long tail, of a rat.—A Keokuk college has purchased it for its museum.

The reverse configuration—that is, a chicken with the head of a rat—was described on page 4, column 2, of the April 17, 1915, issue of the Scott County Kicker, a newspaper published in Benton, Missouri (source):

    Mrs. Tom McNeeley of near Benton was here recently and reported that she had a freak chicken that is blind and has a head that resembles the head of a rat. It eats and follows its mother.

Congenital blindness seems to be fairly frequent in distant hybrids, perhaps due to the disruption of ordinary developmental processes. Such hybrids are often born without eyes. Cyclopean births also appear to occur at elevated rates.
