First time I've ever introduced this early. The Brahma chicks are some big ole chicks so I thought they might be fine. They will be 4 weeks on Monday. I think the hens handled it well. In the video the hens seem kinda of...nervous but I think they are just saying "shut up so we can sleep!" haha. I went out and checked on them a few min ago and all was quiet. I think they are fine now so I'll clean up and close off the brooder until next time!
