Wait till you are an accredited chicken nut and can afford one of those cute ones, to start with, go plain and simple to get you started, nothing complex, it is summer time so you don't need to worry about it being warm right now,protect your chickens from predators and the weather, become familiar with chickens in general and get to a comfortable level before getting into extravigant coops, you are a fairly youing couple with kids, don't leap head first into water ankle deep, who knows, you may hate chickens 3 months from now.
