Just became the owner of 2 Pekin Ducklings. I have made their duck run, but not sure what to use as the flooring. Was interested in using artificial grass instead of pea gravel or hay. What's your thought on it? I have put a 3" layer of sand down, with a layer of heavy weed cloth and now need to cover it. Is 2"x3" welded wire good for the outside fencing?How often and how much should you feed to ducks or just leave food out 24/7? So excited to start this adventure with my ducks. Thank you for any suggestions.
