My first batch (four), are now 10 weeks old. They are in the coop with a covered fenced area to go out in during the day. My second batch (seven) are 2 weeks old, they are in a large box in my house. The first batch have been in the coop for four weeks, they still have two weeks till I let them loose. I want to put the newbies in the coop maybe by next week and I'm just wondering what is the best way to do it. I guess I should try and close off half of the coop for the new babies, but I hate to keep them in the hot coop all day. Do guineas of different ages fight? I'm afraid if I put the new babies in the coop while the older ones are in the fenced area, the olders will never come back in the coop. I know how scared of everything they are. Any advice would be greatly appreciated.
