I use aquariums to raise chicks cause I used to have a saltwater aquarium business, I have a few large tanks layin around so it was obvious. Heres my 2cents though:
1. You will not be able to use a 10 gallon unless its for a single chick as they grow so fast more than 1 will have it outgrown in a matter of a day or 2. Once they are moving around you will have to get them into something bigger. I use a 125 gallon long aquarium for 12-14 chicks (15-18 if they are bantam) until they are about 8-10 wks old. Even with this they start getting to crowded by the time they are about ready to go outside.
2. Aquariums really hold the heat and prevent drafts so I use a 150 watt on 1 end of my 125 gallon aquarium and it suites my chicks just fine. Then they have a large area they can go to thats not right under the heat.
3. Aquariums make wonderful brooders! I like them because I put them in a central location like my family room where my kids play so the chicks get tons of socialization through the glass and are used to a lot more comotion and whatnot and adjust very well to new situation once grown. They are also easier to handle as chicks I think because its not tunnel vision of looking up solid sides to look at the handler, they can see people dead on.
4. Super easy to sterilize with bleech! I use paper towels for the first couple days then switch to shavings. I clean out 2-3 times a week (more if needed) depending on how many chicks I have and I wipe it all down with bleach once a week. I have never lost a chick to an illness or ever had any illness period with my chicks/chickens. I also put the water container up on wood blocks that the chicks can get on to get to the water but they dont get the water as dirty this way. I am building a shelf out of wire this year to keep the food and water elevated above the shavings to make it easier.
5. I keep the light (150 watt on each end) about 2 ft above the chicks this is the top of the tank. From there I move it up 6 inches after a couple weeks then I switch to 75 watt lights at 4 wks. I use 1 light at a time. I use a white light on the end where the food is during the day and a red light at the other end of the tank at night. This seems to keep them on a good schedual so they are quiet and sleep good all night!
This is works great for me so I hope that gives you some info you could use!
Best wishes
