Where do I find chicken coups under $100?

Well my parents have tons of animals. They can be very expensive; medical, cages, food,and etc. If u have a husband or bf or someone even yourself. U can build a simple cage. Buy some boards(for a structure) hinges(for doors) and window net or something to put over the doors to keep the animals in. It'll cost around $20.00-$50.00 depending on the material u buy. Their simple to make and are afordable. But if u cant build then check on ebay cregs list or another site. Theres always something for sale. Hopefully this info is helpful.! Thanks bye(:
