I have 6 chicks in a dog kennel, its size is 2'x3'x2' 3". I know it will be ok for now, but they are growing fast. Check my thinking. I plan to keep them in this cage for about 6 weeks I hope. But if they start getting aggressive with each other I will move 3 out of this cage into another cage until they can go out in the coop (which I don't have one built yet but plan to soon start one). It is still pretty cold up here in Massachusetts so I think putting them out before mid-April is out of the question. Thoughts?
