I just bought 10 Black Langshan chicks (1 week old) and I got the mama hen free. Apparently, the hen isn't very nice. At first, I thought that it would be good for the mama to teach the chicks, but I'm a little concerned that she'll teach them to be mean too. I hadn't planned on getting the mama too. I had planned on handling the chicks while they're young so they'd be nice. Any thoughts?
