I keep chicken starter mash in their coop and in their favorite spot but it seems like they hardly ever eat it. I let them run around my backyard and let them forage for bugs and plants but I only see them eating their mash at night when they are about to go to bed. Oh and i NEVER see them drink any water. I have 3 bowls in my backyard that i fill up with water and it doesnt seem like they ever drink out of them. Am i doing something wrong or do chickens eat considerably less when they are allowed to roam around?
