Hi everyone! I have two ducks, a blue swedish and a black swedish. My mom has decided she no longer wants the ducks to have access to the entire yard. Their poo attracts too many flies, and we also have non duck friendly dogs. My mom likes the ducks, so she doesn't want them getting eaten. So we were planning on fencing off a 15 by 20 foot area for them to roam in all day. We also want it to look nice in there, so we wanted to lay sod down so it was nice and green, and so it wouldn't hurt their feet, as we have bark in the area now. So would the grass stay nice looking being that its 15 by 20 feet and only two ducks, or would they still completely wreck it? All answers are helpful! Thanks!
