Temperature is another thing I'm curious about. I've seen it listed that chicks should be started out at 105 but other places say 95. Thoughts?
Assuming you're talking about ambient temps (heat lamps) I personally feel 95 is a little too high and something closer to 90 is good for the first week. Whenever I see photos of plastic tote brooders with the heat lamp inches away from chicks, they look like little chicken nuggets under a broiler to me.

Chickens are far more sensitive to heat than cold and that applies to chicks as well. At 105 I'm guessing you'd see a lot more pasty butt, maybe panting and diarrhea from too much water.
