New here but wanted to share this info...
My ducks, ( pair of spoiled Rouen, Buddy & Squeek) absolutely HATE all things BLUE. I noticed when they would go nutz every time I carried this blue bucket into their area....they freaked out and would scream and run in circles. Once I understood it was the bucket,. I then learned it was the color that bothered them. I had seen them react to a brown stick (snake) and other things that made sense, but the Blue thing is baffling. Even the plastic blue broom gets them upset....
Every so often I forget and wear a blue T shirt out there and pick up Buddy...and he starts chewing on me and acts like I stole his dinner...till I remember its the blue shirt that he's reacting to, not me.
