I ordered a pair of buff goslings, 6 runners, a cayuga female and a buff female. These are my first goslings. Anyway, I put them in the brooder and they start going crazy in their waterer. Not surprising. So a few of the ducklings got themselves sooo wet, and I see the female gosling picking at them. I thought she was being mean, but then it looked like she was just trying to clean them.... Is this normal? I don't want her to hurt the little guys!
