I have 10 7-week olds (still gotta give the roosters away even though I'm attached ). My hubby is still in the process of building a coop but can only work on it on the weekends, weather permitting. Since day 1 these "babies" have been in a watermelon box brooder on our back porch. For the past few weeks or so, every day I get them out of the watermelon box & put them in a cage & take them out & put them in what I call their "playpen". It's a chain-link 6x8 dog kennel (4 ft tall) that has a piece of metal on top of the back half as a make-shift roof like if they need shade or if it comes a shower, etc. There is a hanging waterer out there & I take their feeder out there from the watermelon box. Then, at night, load them all back up &'put them in the watermelon box brooder. For the past week or so, I do the same routine except I leave the door to their "playpen" open where they can free-range with the other chickens. It's been working out great. The older chickens have gotten used to these "babies". At dusk, when the older chickens are going to roost, the "babies" go into their "playpen". Then, I close the door, catch them & put them in the little cage & tote them back to their back porch watermelon box, put their feeder in there, etc. They do have a little roost in the watermelon box. Do I just keep doing this until the coop is built or should I put some sort of make-shift coop for them in their "playpen"? I do have a small dogloo dog house & I have a small pet carrier that could go in there if needed. I wasn't sure what to do, but they're getting way too big for the watermelon box. I do have a smaller "coop" that hubby had built for the now teenager chickens that is no longer being used. It is not where it can go in the "playpen" though. It's too tall. Also, the inside of it is not near as big as the inside of the watermelon box.
