Heartwing Dock/Sorrel (Rumex hastatulus) for Chickens & Ducks?

[PinkBlanket]

Hello,

I have a ton of this growing all over my property. I took a bunch and gave it to my chickens and ducks and they devoured it. I looked it up this morning just to be sure they can eat it in larger quantities before I go out there & give them a few lbs of it with their regular feed and I'm not able to find much. Have any of you had experience with this? Thanks!

I would limit it, here is some information for humans. You are dealing with mineral imbalances so it probably applies...

: Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet s
