I got two new chicks. The problem is that I am going to put them with my other chicks, who are 6 weeks older. There are roosters in my older chicks, so should I keep the chicks with my older batch of chicks, or separate them until they become big enough?
Edit: They are about 3 or 2 week age difference, but the new chicks weren't raised on chick starter so they are heavily undersized.
