We just enlarged our coop. Started out with an 8x8 and had 8 RIR's in it. Now it is 16x8 will be adding 3 barred rocks in there in the next couple of days. Also the juvie coop we enlarged to 14x8 one side for our 7 9 week olds the other side I am going to be putting our 6 5 week olds in soon. How many more chickens can I safely put in the larger one as I have 3 bantams that will need to go out one day and when the 9 week olds are older want to transfer to larger coop and I have 23 RIR hatching in lockdown right now.
