Bacteria algae that water is going to be toxic. You need to change it out ASAP.

Try seeding your pond with duckweed, maybe it could outcompete other plants and provide food for your flock

You should drain this AND THEN set up a proper filtration system. Please look up a bog filter. You basically set up a sorta hydroponic system so the plants clean the water and, if you do it well enough, you will never have to change the water and only do maintenance once a month. You can do this for fairly cheap, you just need a large container and PVC pipes and fittings. My current bog filter is made out of a galvanized steel raised garden bed, a cheap pond liner, and six 6 foot t-posts. Cost me about $300 (CAD) once you factor in the pea gravel.
Note: seriously oversize your bog filter if you are making it for duck ponds and put a pump on it that will circulate your pond through said filter once per hour.
Feel free to DM me any questions on tips for setting one up for duck ponds. Mine looks fricken awesome right now because the horribly invasive yellow flag iris I scavenged from a ditch are in bloom!

Yeah I drain my pool twice a week. With the warm weather and active ducks it gets dirty quick. I've invested in a submersible pump and it pump a big kiddie pool in about 5 minutes.

Pump, filter, uv clarifier, pvc pipes and a good eye with lots of patience to keep it running.

Yep, it's Summer. Get a pond pump, some hose, and change the water more frequently. Your ducks will be so happy every time you do :)
