This is a very strange question, but thought I'd ask the "pros" since I can't find anything else about it on the internet. We have a large dirt yard where we keep the chickens, my husband does all the weed abatement and is very familiar with most things that grow there. Recently we've been findng small round patches of some different kind of grass, and when he pulls it up it is a bunch of sprouted seeds. Never seen this before and wondering if the chickens (they're only 3 months old) can "plant" seeds? They seem to know where they are located and scratch them up to eat and cover them back up! The seeds do seem to look a little like some that are in the scratch we feed them. Anyway my husband is amazed and we are very curious to see your posts. Thanks!
