Good morning! To give a little background I bought chicks about 4 months ago straight run and and ended up with more than I wanted in roosters. So I got another batch a little over a month ago. At week 6 for the new chicks, the brooder I was using quickly became too small. I underestimated how fast they outgrew the brooder without being the same size as my older chickens. The size difference is staggering. Naive me thought that I’d be able to integrate around this time but have since read otherwise. (Because of size difference) I’ve bought a larger brooder/pen and moved those 6 week old chicks to the garage with the lamp turned back on. So here’s my question: Should I build another smaller coop for this transitioning period until they’re up to size and can more readily integrate? I feel they’re going to outgrow this new playpen area quickly. Here’s a photo of their pen area. Please excuse the mess.
