I have four Indian Runner ducks that I bought as hatchlings 3 months ago. I raised them in a brooder but swam them in a large stock water tub every other day....They loved it. After they were mostly feathered I moved them to a large pen with free access to the water tank...they loved it. 2 weeks ago I moved them to their new coop next to a large pond and they hate it!!! It is stocked with fish and every time a fish or frog splashes they come unglued and run for their coop. Seriously?? They stand and look longingly at the water but refuse to go in. Help! Has anyone else had this problem?
