Are they feathered out yet? If they are, they'd be fine out in the garage with a heat lamp. If they are crowded or uncomfortable, that can cause them to exhibit bad behavior. Or they are just being rambunctious chicks. How many do you currently have? (If you stated this earlier, I apologize. I'm a few pages behind).Ok I know this is me being a novice with chicks but they really stress me out! Not sure it's the mix of breeds or what but I feel like they are all nuts! The BCM is getting so big so much quicker than the others! The Mille Fluer thinks he's the boss and is picking on the others ( pecking the feather/fuzz out of the Ancona who is a total mental patient ) the poor little peaceful jaerhon are constantly being jumped by somebody! They will eventually all be together so I hate to separate them now only to have to reintroduce them later any advice I have a bunch more coming soon! I have 2 larger totes connected with a roosting bar, a dirt bath,treat stick and hay for them to scratch around in. I was hoping to have them out in the garage in a bigger container soon but with this weather I don't think they are ready? Just over 3 weeks
