It's good to get the chicks outdoors. I don't put my juveniles out to integrate with the existing flock until about 5 or 6 months old when they are at their adult height and just need to fill up muscle later. When integrating you can use a rabbit fence to separate the juveniles from the adults and let them see each other as they forage before removing the barrier fence after a few days. The juveniles will have their own safety "cliche" group and the adults will have their own. Before you know it they are all intermingling during foraging with new pecking orders to learn. Nice chick brooder. That row of trees/foliage is awfully close to the coop - do you ever have prowling critters in that greenery?I had to get my three Golden Comets and five Black Stars out of my house! Chick dust everywhere. So I put the Juvie coop together without any real plan. I knew I wanted vinyl flooring to pull out and clean, suspended cooler with waterer nipples, hanging heat lamp and pvc feeder. It came together fairly easily. The girls are four weeks and five weeks old. They will stay in there till they get closer to the same size as my existing flock. Until then, they will have to verbally and visually figure out peaking order. Only thing I need to add are some slats/stairs for them to get in and out. The coop is four foot by five foot. Lastly, a word of warning, if you've never used corrugated sheet metal, the stuff will cut you by just looking at it.
