So...we upgraded the ducks to a larger pool a few days ago. That same day and the next two, they spent nearly all of their time floating, swimming, and had a blast. Two days ago, I drained it and filled it back up. Ducks have not gone in. I put one in today, the other two jumped in shortly after, were there for about 3 minutes and jumped out, not to return. Maybe they just don't want to be in water, but it's so strange because with their old pool, AND this one, when I first filled it, it was nearly every moment they could be in it. Last two days - nothing. Thoughts?
