Here's my notes on chick heat, hope something in there might help:
They need to be pretty warm(~85-90F on the brooder floor right under the lamp and 10-20 degrees cooler at the other end of brooder) for the first day or two, especially if they have been shipped, until they get to eating...
As long as it's dry and out of the wind they should be fine.
Consider making them a 'huddle box', put it in the brooder after turning off the heat(you might have to 'persuade' them to use it) then move it out to the coop with them.
Cardboard box with a bottom a little bigger than what they...
You should have already started ramping down the heat to wean them off of it.
Keep a window cracked and the heat off in the brooder room so they get used to cooler ambient temps.
Depending on how cold it is outside, they probably wont need heat in the coop.
I use both.
Lamp during day for first couple days after hatch, heating pad for nights then full time after first couple days.
HP is great fantastic for smaller number of chicks(depends on size of pad and configuration).
Large number of chicks(20-30+) lamps will be more effective.
