Ok, I am in MS so my cold nights are not like nebraska cold nights. The coldest night the chicks spent out in this brooder was in the mid thirty degrees F outside. It started out as a 4'x3' frame this is 2' tall. On cold nights, I prop up some wooden sides (actually use a plastic tote lid on one side that fits.) All closed up, it looks like this:
When it is warm enough (it is mid 70's now) I can take three of the sides down. (the back is solid wood.) Like this:
There is a piece of tin nailed on top to keep the rain out. can you make out the bungy cord on top of the tin? When I want to get in, I pull up the tin and attach it to the fence behind the brooder with the bungy cord:
Underneath the tin, there is a plywood top, half of which is hinged for a door. I open the door to get access to the inside.
There is hardware cloth stapled to the inside of the brooder to keep the chicks in. There is 2"x4" weldwire nailed to the outside of the brooder to keep dogs and other predators out. (I actually did have to go outside one night, months ago with a different batch of chicks, to chase away a dog who was trying to dig into my brooder. So that's why I added the weldwire. The weldwire also wraps all the way around the bottom of the brooder, so if a dog did dig under, he still wouldn't be able to get inside.
Below is a shot of the inside. There is a block for them to climb on. The water can is suspended above a large wooden block. It stays remarkably cleaner this way. They have to hop up onto the block to get the water. When I open the door... up comes the water can so I can clean it and change it.
In one corner is a box (the box the feed store gave me when I bought the chicks) I have the top of the box open, but with a black shirt draped over the top of it to help it absorb heat (and keep it darker at the same time so the chicks can sleep) I also insulated around the outside of the box with a few magazines to help it hold heat. There is a heat light suspended above it.
Below is a pic of the inside of the box. It is currently lined with paper easter grass.
Very festive! lol
And here is a picture of the chicks playing around. I actually put more dirt in the bottom of the brooder to cover the wire (which is big enough for them to fall through.) They like it in there!
I never checked the temperature when we were having those cold nights, but I did check on the chicks frequently. They never bunched up or seemed distressed. Even when it was coldest outside, when I would go check on them (disturb them from sleeping) they would always act like they were comfortable and happy. I am pleased with how it worked out.
