Go for it....you will enjoy watching them as much as they will swimming and playing in the water. Throw a handful of peas in the water for extra enjoyment.. i always love watching my guys dive down trying to find them. They will get waterlogged pretty quick since they dont have feathers yet - but a few minutes play time will be good for them- give them a quick rub down as you take them out before putting them back into the warm brooder.
