This is my article on setting up an outdoor brooder, plus integration tips and timeline. My personal goal is to have chicks integrated and moved into the coop with the adults at around 4 weeks. There's several other articles listed at the bottom as well, so you can get a good idea of what works overall, and how you can modify things to work in your set up. https://www.backyardchickens.com/articles/short-on-time-recycle-a-prefab-brooder.73985/I would love to know how to integrate them earlier next time. Can you suggest how to do this or suggest reading materials on this method?
