Can you put the 2 ducks in with the chicks and then everyone can use the pool? Then there wouldn't be over crowding. They could huddle if they want, but would have room to move, too.
As for the deaths, hard to say. Maybe stress from shipping? Maybe an illness. I wish I could help you there. It's so hard to lose them.
