So I have a flock of 15 ranging in age from 3.5 weeks to 1 week old. They get along just fine, but the bigs are starting to knock over the food and water containers. They are already raised up and a brick (and the littlest ones can JUST reach it). My question is, should I separate the biggest girls from the littles in another box with a larger food and water container or with this be detrimental to the mentality of the flock when I move them to the coop/run? (They're still in my garage with their heat lamp for the next several weeks).
