I know I should remember this, but at what height should I keep their lamp away from them? I remember the rule about they'll huddle if cold, scatter if too warm. But they're kind of divided, so I'm confused. I don't want to fry the close ones, if it IS too close. Please help. The other question is something that we haven't dealt with in the past. We've got a black lab this time around. 6 months and baby chicks. Is this just a disaster waiting to happen? Can they learn to coexist? What's the best way to deal with this scenario. I appreciate any help!
