We donated some duck and chicken eggs to a teacher friend for her class to hatch. They got two chickens and one duck hatched and returned to us The duck thinks he is a chicken....he even trys to sound like one. They are big enough now, that we are introducing them to the ducks and chickens we hatched earlier. The 6 older ducks are VERY interested in him, but he is scared of them. He hangs in the corner with his two chickens. I am hoping that they will all get used to each other soon.
