Can chickens eat parrotsfeather and hornwort?

[Gypsi]

I scooped most of the parrotsfeather and hornwort out of my pond this morning. They aren't toxic to fish, figured they would be ok for chickens so I tossed a pile, snails and all, in the chicken run. If I need to go get them out, someone tell me quick. I also gave them a pile of chickweed, wild carrot and annual rye, and chick feed, so they aren't going to eat it because they are starving.

Well…???? How did they do?? I am in a situation where I have an abundance of hornwort (Hornwort Ceratophyllum) can I feed it to my chickens??
