Chokecherries are toxic to most mammals..the pit contains arsenic although the flesh is very tasty. They even sell pints of chokecherry juice now in my neighborhood..but I'm wondering about a passive feeding arrangement for geese and ducks..anybody have any experience feeding geese and ducks chokecherries? Toxic or no? BTW anybody have other suggestions for shrub sized quick growers for such an arrangement? Hackberries? Mulberries¢? Shredded honeylocust pods? How about acorns? Many thanks...
Hmmm, I wish I knew about the choke cherries! I do know that my ducks like eating blackberries and other cane-type berries (like raspberries), as well as strawberries (they eat the berries but not the plant).
I've heard of people planting mulberries for their ducks/chickens, and it being a good source of protein, and it has berries for a long time. Mine still haven't started producing (I think it's something with my soil, since they had berries when I bought them three years ago...)
You could also try planting some buckwheat or other grains, as they really like eating the seeds when they ripen, and if you're lucky, they might reseed, too. My ducks refuse to eat any brassica leaves (kale, broccoli, wild mustard, radish), though they do munch on them a bit when they go to seed or have gone through a frost.
