Notsuperwoman,
To answer the question about what size brooder you need. Here is what i have:
With a total hatched is 19 yesterday and today and the 35 Carl hatched for me, and the 7 hatched mid week last week, there will be 61 in the 38 x 45 inch brooder.
They will stay there until 2 weeks of age.
Then they will move into a 4.5 foot by 7 foot floor pen for two weeks.
Next they will move into the floor of the brooder room or outside depending on the weather for the next two weeks. The brooder room is a 12 x 11 foot room with wall cages for breeding and brooding babies under lights and includes the floor pen....so square footage for the play space is about 100 square feet. This area can handle several hatches.
So far the chick living arrangements are
61 in the brooder
46 and a hen In the floor pen
35 on the brood room floor..they think they are in heaven with so much room.
When the next hatch comes in two weeks..the groups move again.
Each area has a heat lamp set at different heights according to their age and ample feeders and waterers.
in the past, I've used a wash tub with a screen cover, a cattle water trough with a screen cover, a big cardboard box , a used baby play pen. You can be creative, you simply need a safe heat source and room enough for the chicks to move about safely without escaping and protection from the curious pets or predators as well as something easy to clean up after the chicks.
