Are Lily of the Valley Toxic to Chickens?

[The ThymeKeeper]

My chickens eat the heck out of Lily of the Valley leaves. The plant barely gets 3 inches high and the leaves are gobbled up. No ill effects, thankfully.

I just found that l My three gals mowed about 9 Lily-of-the-valley plants right down to nubs. I am aware that every part of the pretty smelling plants are toxic. Incredibly so. They clearly snuck up on me this week we went from 35° to 87° and I’d missed them. Argh All three hens all have—let me just say—Remarkably Explosive Diarrhea. I’ve dosed their water with electrolytes to combat any dehydration from the poisoning and diarrhea.
Just so people know, Lily of the valley Convallaria majalis are not in the Lily Lillium plant family.
