Okay, here is the info. I will see if I can transfer the pic, too.
**************************************************************
I have a shelf with solid metal shelves, but you could just put a board on top of
the shelves if they have holes.
I put wire around the whole thing, and built a frame for the doors with wood. It has
3 shelves about 14 inches tall each.
I hung a metal work light fixture from the bottom of the shelves. If you can wire
it, it hanges better. I tried using duct tape but they keep slowly coming down. Keep
the metal shades on the lights. The chicks can gather under them if they need the
warmth.
I put the waterers near the lights so they don't freeze, but really, it stays warm
in the whole thing.
I used a canvas tarp because its heavier than plastic so the sides hang snugly to
the shelf. I used big plastic clips to hang the tarp to the top of the shelve and
overlapped the ends in front of the door for easy access.
When I wanted to openthe doors or take a peek, I just let one clip off and let just
the area of the door open.
I used shavings for the bedding and had to clean it out about every 2 weeks or so.
My shelf is about 5 feet wide by 16 inches deep and 5 feet tall. I could keep about
20 chicks in each section. When they got bigger at around 3 weeks, I moved them to
a floor brooder with a heat lamp.
I had the top shelf with 2 lights because that is where I put the chicks right out
of the hatcher, so it was warmer. Then as I put the next batch in, I moved them down
to the middle shelf, & so on....
edited to add: I think this can be modified in many ways, but I like the idea of the metal serving as a heat conduit. I may just go ahead and try to find an old metal desk or something and cover the whole thing since I am not staggering hatches.
I also do not know the wattage of the bulbs. I will try to bug Richard one more time....
Hope this helps!
