so we bought our first house!! and as everyone who has ever bought a house knows you never find 100% of everything your looking for. we are on a time limit and my concern is how to house the chickens. dh cannot build anything(i am not kidding!) and we are a little wipped out money wise from the purchase! so my sister has a rubbermaid building(from sears or lowes) that she is willing to give me for a coop. it is completly plastic, even the bottom. the front swings open and the top slides halfway back to open. im not sure exact size but it has a large riding mower in it with a little room around it. its maybe 4 1/2 to 5 feet tall. how can i turn this into a coop? the bottom is even solid plastic, which will be nice for cleaning and i could just add roost and nest boxes, but what about some type of ventalation? what else would it need? it will be home to 6 chickens.
