We finally got the bottom brooder finished and most of my babies moved out to the big coop *Sniff* The brooders are both about 4ft wide x 3ft deep x 3ft high. I am happy the chicks have more room to run around, but its harder to keep running out there all day to talk to them lol. The bantams (most from TSC) have the top, the standards (mostly pullets from Ideal) are in the bottom. Think there is about 30 in each. I still have some tiny bantams inside for a little while yet, so I'm not totally going through chickie withdrawal yet lol.
