@azygous did a great job in her article about the benefits of brooding outdoors! Hubby just got the portals cut and framed into the brooder pen, and I'm excited to use them rather than just trying to prop one side partly open during integration. In the article I wrote, I was talking about the "hows".A really great article, I've been reading the huge mama heating pad thread. Good stuff there too!

I also brood chicks outdoors, using Mama Heating Pad, and I'll never go any other way. But I'm the first to admit that it's certainly not for everyone, and don't try to "covert" folks who might not be comfortable with such a drastic change in doing things. The way I look at it, there is no absolute "right" or "wrong" way to brood as long as the result is healthy chicks! We sure welcome anyone who wants to stop by the Mama Heating Pad thread and check things out! Good group of warm, friendly people over there!
