I want to make a second coop for housing my babies-4mo or so (old enough to start eating layer feed). I have to do it as cheaply as possible, and also as simply as possible as my husband is going to be out of town and I have 3 small children to take care of. I currently have 4 standard size chicks, and I'm expecting another 5-6 bantam chicks and another standard in the next 2 weeks. What size should I make? I keep seeing all these neat repurposed coops with things like old dressers and dog houses and such, but I don't know that any of those will work for the number of chickens I have.
