Sometimes I make things for my pets. Like cat beds, cat toys, pots of kitty grass, painted pots for the kitty grass or catnip, dog collars, dog sweaters or coats, dog snacks, dog beds, parrot toys, parrot playgyms, a chicken garden, an improved fish pond or anything else I can think of!
Some stenciling or decorative painting on a coop is fun, too. Do your ducks or cats need anything?
Bird feeders don't have to be big and fancy. They can also be a simple tray that has drainage. I have one that's just a simple wood frame with window screen attached on the bottom, that hangs by three chains (could use rope) that connect at the top. The birds love it!
I also made a feeder by taking a log and drilling some big holes in it. I packed the holes with a peanut butter and suet mix, that had some raisins and nuts mixed in. I might have put a bit of cornmeal in there, too. I put a big screw eye in the top, to hang it. They loved that one!
Maybe you could wander around your place and see what you have, that could be turned into something else. Sometimes that inspires me.
