I have three brooders I use.
1. Is the spare bathtub/shower. The sliding doors are great at keeping both chicks and heat in.
2. A 90 gallon aquarium on my screen porch. The older chicks go out there to start getting them used to cooler temps
3. A LARGE plastic storage box. This makes an excellent brooder. If you have cats, you can cut the top out and attach hardware cloth for ventilation. Just hang the light above the mesh. The top will snap on and the wire will keep critters out. The plastic is so easy to clean, too.
I finally got some photos of my latest five chicks. 4 purebred Americaunas and one standard blue cochin
#1. "lavendar Americauna (not a recognized color....yet!)
#2 another lavendar
#3 a wheaton. It was sold to me as a blue, but I think it will be a wheaton
#4 Another Blue/wheaton
#5 My blue cochin. You gotta love the feet!
