You have an article too, right...link it here maybe
@blackdog043 has a good setup too.
Both of yours are simpler than mine...I should link your articles in mine.
I really should do a separate integration article... maybe "next time" so I can add more photos.

The setup is relatively simple because I just used what I already had around. If I added chicks on a regular basis I would've had a brooder built into the coop, but I don't, so having things that are temporary suits me fine.
