If I ever get a rooster again and have a Layer that wants to go broody, I would be happy to have baby chicks. I would rather try to do it the way of nature than with a machine. Having the mama their to say “welcome” is just so wonderful. But, if I don’t get back out to the country soon, then I will have to resort to using an incubator. But natural birth is always best in my book!
