This is the story of a parrot's egg - and a flirtatious wife and a jealous husband. Jack and Edna's pet parrot lays a huge egg - one much bigger than parrot-size - and promptly dies. Jack and Edna keep the egg warm, and it hatches into a menacing, black-feathered bird. Although it fails to talk, the new arrival soon begins keeping a close and disdainful eye on them... Jack befriends the bird, but Edna is unnerved by it - and she has good reason to be. (thetvdb.com)
