Sheep-Goat Hybrid Born: ‘Geep’ Is Rare (Source Inquisitr) A sheep-goat hybrid known as a “geep” is stealing hearts at My Petting Zoo in North Scottsdale, Arizona. The baby ball of fluff is named Butterfly, and she’s lucky to be alive — according to Buzzfeed, sheep-goat hybrids are usually stillborn. Goats and sheep have a hard time making babies together because they have different amounts of chromosomes and are from different genera. However, when they do succeed in mating, the result is pretty adorable. The female sheep-goat hybrid’s mother could be featured on an upcoming episode of I Didn’t Know My Pet was Pregnant. According to AZ Central, My Petting Zoo owner Priscilla Motola didn’t know that Momma the sheep was knocked up because there are no male sheep in the petting zoo. However, there is a male pygmy goat named Michael, and apparently he didn’t care that he and Momma the sheep are genetically different.
