I was going around identifying some plants on my property (PictureThis is a fantastic plant/insect ID app) and I have a ton of blue fescue. I'll try planting some in the duck pen and report back on how it fares.
I need to figure out some good plants for my pen too. I transplanted a bunch of clumps of squirreltail (wild rye grass) around their pond to make it nicer for them, but I'm sure most of you can guess how that ended with 10 hungry ducklings around. At least they had fun though.
Someone on here...
