I know that this hasn't been replied to since November, but oh well. Thought I'd share...
We are gathering materials for a new 12 x 10 coop, with a 14 x 20 run. This should hold our current layers (assorted breeds) and the currently 6 1/2 week old Delawares. Then I plan to hatch Wheaten Marans, BR's, Blue/Splash and Lav project Ameraucanas, and assorted Silkies. When they first move in it will just be a large coop, but I hope to divide it and the runs into pens for breeds later on.
I have a large brooder (6 x 7?) ready, and another one that are shelves made into two sections. They've been empty for a week now, and I miss having chicks in there.
Then the coop I have now, 5 x 3 with a 14 x 6 run should be a grow-out coop. That is unless I get Blue/Lav Orps from bargain. Not sure of that yet.
These will all be breeder quality. No more hatchery for me. At all.
