Ok, dumb f.u_cks. The people who wrote the Bible did not in fact speak English. These animals would've had different names in whatever dialect of whatever language they spoke, and the name would NOT have been rude, judging by how zealous you weirdos are.
Also, words like 'co.,.ck' and 'p...oo' used in the context we see today are modern slang that originated far after the naming of these animals. At the time of their taxonomy these names wouldn't have been vulgar in the slightest.
