I've got 7 12 week old growers that my broody hatched out in January. At the moment they are in a separate coop and run to my 3 adult girls. I would like to put them all together as the growers really want to get out of the run. I've just finished a 1000sqft enclosure for them all and the adult birds have been in it for a week when they are not free ranging. I've a separate coop set up down there for the growers. How do I go about mixing the 2 groups? Mamma hen has been away from the babies for about 4 weeks since she was really wanting to get out free ranging but the babies weren't big enough to stand up to my cats.
