I am getting baby chicks soon from meyer hatchery I have a inside brooder set up but once they are fully feathered and not quite ready to be put in with the big chickens I was thinking about a chicken tractor but one thing stopped me, the safety. Are chicken tractors safe enough for a even temporary solution. Are there any that are safer than others and what other solutions will work beside getting a chicken tractor? I was thinking a xxl dog crate but what about a pen?
