Put a brick both in and on the out side of the kiddie pool.Speaking of water... I've given up on our ducks using our stock tank so I'm looking to get a kiddie pool from Wal Mart. How high from the ground into the water is safe for a duck to step? From the water to the ground? I've seen some pools with steps leading to the water but am wondering if folks use anything on the inside to assist with them getting out of the water? Thanks for any advice.
