Ya, I will have to keep chemical levels down sense the birds will be drinking the water so the chlorine will have to be kept down to a minimum. When I shock every know and then I'll have to do it while there out and fence them out for that time until levels drop to normal. There is already a fence around it with a gate that I open everyday to allow them to roam in the yard. Anything you or anybody else would like to add would be excellent. Thank you
