I am investing in a lot of chicks this year and will be selling them at the flea market and through adds. I am wondering on what I could use to house 100-150 chicks at a time that can be portable and go on a flat bed trailer and travel about 20 minutes to the market. We thought about doing crates that were 4 ft long and 2 feet wide. Will this be enough room and is there something else I can do besides building crates ? Any suggestions and pictures of what you do would be great ! Thanks !
