Baby chickens do not care about waterstreams.

I made a chicken farm, and I expected the chickens and baby chickens to flow down to my hopper.

The chickens was pushed to the hoppers, but the baby chickens ran around like it was no water there.

Make a 2 deep 10x2 hole, put water in one of the ends and breed two chickens to make a baby chicken. The baby chicken wont swim and act like its no water there
