A theory....

[micah wotring]

I have 4 muscovy ducks and one that's.........not...XD Had a couple people say she was a magpie and a couple say she was a mule...not sure... Anyway, she's always the first one to go to the duck tractor when they see me coming every evening. The others always follow her. Also, every morning I let them out of the tractor and walk up and toss some feed out beside the chicken coop. The other ducks just stand right outside the tractor until they hear the feed but she follows me up to the coop.

Hm.....but all those ducks are about the same size....
I was really looking for someone who would know if the brain size is really bigger, or if its like the wings on ducks.....big enough on mallards, but too small on anything bigger, you know?
Thanks anyway Micah, your results have been duly noted in my study
