The article I read said people could eat mallow in salad. Maybe you need to offer your flock some dressing options?

The weeds my chicken let live in their run seem to support butterflies. They are evil geniuses. Yep they farm.
Nope my chicken are farming some type of Spurge. Were it milkweed it would be moved to our butterfly garden.
They never were weeds just under appreciated plants.Your chickens saw your butterfly garden and decided to build their own? Impressive!
If the weeds are doing some good, maybe they’re not weeds!
I will try that. Thanks@LakeGooseBerry
Spread out some Wheat Straw and the "wheat" grass that will pop up will over take the weeds AND your chickens will love the "wheat grass".
