Here is pics of my brooder. Had to use what I had for now so... here is my dogs travel kennel, top and bottom put together covered in plant netting held on with clothes pins.
Here is our brooder for 6 BO's. An eighty gallon aquarium and stand we just happened to have in the attic! Its working out perfectly - dust is not a problem at all because of the solid sides. Its like a chick tv because it offers complete visibility - since we have it in the living room we notice the chicks watching US sometimes, lol. I was a little worried about temp control, but i monitor the thermometer (and the chicks' behavior) closely ; and we have the heat lamp clipped to an 8 ft 2x4, so we can really adjust it much higher if it gets too hot, and so far we've had zero problems. Also, here is our play pen, which my Dad and i threw together out of scrap last week. Its a bottomless 4x4x2 pen with a hinged top. I just move it out to the yard and the chicks get to spend a lovely, warm afternoon scratching and testing their wings to their hearts' content. So far all six are happy and healthy!
