I'm getting chicks this spring for the first time.... I'm getting 6 chicks.
		
		
	 
	
		
	
	
		
		
			I found this on the internet.  I think it will address the brooder space that some of you have pointed out.  This will give me almost 16 sq ft.
		
		
	 
Do you have their coop yet?
I would suggest just brooding in the coop, if you can run an extension cord out there for electricity.
Then you will not have a big brooder, that cost money and takes up storage space, once the chicks are done with it.
If the coop provides 4 square feet per chicken (or more), that amount of space is fine for chicks too. Block them into a smaller place for the first few days so they learn where the heat, food, and water are, and then let them have the whole space to explore.
Brooding in the coop saves you all the bother of setting up two different spots.
It makes sure you HAVE a coop by the time the chicks are ready for it.
It is very easy to acclimate the chicks to outdoor temperatures: just leave the heat source in one corner until you see that the chicks never use the heat, then remove the heat. All done.
	
		
	
	
		
		
			If I put this in the garage, it will be on concrete.  Will this be a concern, or should I have some plywood down first?
		
		
	 
When I have brooded chicks on a concrete garage floor, I put down this:
--tarp to protect the floor
--cardboard over the tarp, because I didn't want chicks directly on plasticy tarp
--bedding on top of the cardboard ("bedding" was paper towels in the first few days, and after that I added lots of dry leaves, some clumps of grass with dirt attached, a few shovels of loose dirt, etc. This seemed to work great for the chicks, but everything else in the garage got covered with a lot of dust.)
I used a heat lamp in one corner of my brooder space, which was 4 feet by 6 feet. Some chicks were running to the far side of the brooder by their second day after shipping. Since the heat lamp warms the floor underneath it as well, and I started it running the day before the chicks arrived, I was not concerned about the cold concrete floor.
Some people say heat lamps are bad because they provide constant light.
I will point out, that same light attracts the chicks to the lamp, so you do not have to train the chicks where the heat is. A broody hen does not make light, but she does cluck to call the chicks. So they get some guidance that way too. A heat plate requires the chicks to learn what it is without the guidance of light or motherly clucking.
And chicks under a red lamp DO sleep at night (evidence: late-night checks by me. After the sun goes down and other lights go off, the chicks lay down to sleep until morning.)
Heat lamps are not always the best choice, but I think some of the points against them are overstated by people who do not use them and never have used them. I see the main problems as being too much heat for a small brooder in a warm house, and risk of fire from a heat lamp that falls down. (Yes, I personally know someone who had their chicken coop burn down because the heat lamp started a fire.)
