I'm going to go to the feed store tonight to pick up some more chicks. They'll be the same age as my current chickens in the brooder cage (2.5-3 months). I only have one huge brooder cage (7'x4'). I currently have the 3 guineas, 7 hens and 1 rooster in the brooder cage. I am looking to pick up another rooster (from a neighbor) and more hens. Should I look out for any problems? Would I be okay mixing them in the same cage right away? Should I get another cage to set beside the current chickens for a few days? Any suggestions are greatly appreciated!!! Another question: I have the two Silkies (or random bantams) separated from the standard chickens. Could I put them in with the standard chickens in the brooder cage? They can't directly see each other, but they can hear each other currently.
