I am new to raising chicks. While I’ve hatched 4 batches this is the first time I am raising some past 2 weeks old. I’m down to 4 boys 
They’ve been in a big brooder box on a table in the family room but they’re getting close to flying out, need more room, etc. I’m using the mother hen heating pad method - love it!
Here are a few pictures of what we set up. It’s a section of the shed coop 25 gold stars and a SLW roo use for their roost, feed and water, and nesting boxes. It’s plenty big. It’s attached to a huge run and they come and go freely at all times.
The first 3 pics are of the brooder area right now. I started with the crate and made it into the unheated cave on the right side in the top pics. Then I got worried about it not being heated so added the heating pad cave they are used to (left side of pic).
Question: will they get confused on which to use when needed? Should I remove the unheated cave? The chicks are 13 days old.
I took them out for a few hours over the last few days to acclimate them to the space. They LOVE it! Running around, seeing the big girls, etc. The roo checked them out briefly but doesn’t seem that interested. Some of the hens are quite interested
. They’ve been in their area most of today.
I’m planning on keeping them there all night tonight for the first time. I’m nervous as heck!
Also I ordered some chicks that will arrive Tuesday or Wednesday. We’re working on a table level brooder that will go against the shed wall over top where the current floor caves are. This is so the new chicks start in the coop but separate from the 2 weeks old chicks. Having all the chicks in one location should be easier on me. In a few weeks the new chicks will move downstairs and be integrated with the older chicks. Well, that’s the plan!
I’d love any feedback and suggestions on whether this set up makes sense or needs adjustments. Thanks!
