The chicken dance and the funky chicken are two different songs and dances. Only the chicken dance corresponds to the Ententanz.
From Wikipedia:
The "Chicken Dance", also known and recorded as Der Ententanz, Tchip Tchip, Vogerltanz, the Bird Song, the Chicken Song, the Birdie Song, the Bird Dance, Danse des Canards, the Duck Dance, El Baile de los Pajaritos, Il Ballo del Qua Qua, Check Out the Chicken, or Dance Little Bird, is an oom-pah song; its associated fad dance is now[when?] a contemporary dance throughout the Western world. The song was composed by accordion player Werner Thomas from Davos, Switzerland, in the 1950s.
The Chicken Dance is a well-known drinking and dancing song at American Oktoberfest events. It is also a popular dance at weddings, particularly in the regions of Texas that were settled by German and Czech immigrants, and who retain a strong love of polka music. Over 140 versions have been recorded worldwide, including some that were released by Walt Disney Records, together making an estimated 40,000,000 records or more pressed.
The original name of the song was "Der Ententanz" (The Duck Dance), by the Swiss accordionist Werner Thomas. He played it in restaurants and hotels from the 1950s through the 1960s.
"Do the Funky Chicken" is a song written and recorded by American R&B singer and entertainer Rufus Thomas for Stax Records in 1969. The song was used as the title track of Thomas' 1970 LP, Do The Funky Chicken.

The two YouTube performances make extremely clear that these are not the same song or dance. "Do the Funky Chicken" is R&B; "The Chicken Dance" is oom-pah.
As a former German teacher I have danced and taught "The Chicken Dance" hundreds of times. I have never danced "The Funky Chicken."
