did you put a 2x4 thru the can or something for them to roost on? or is it just the can they sit on/in? how do you keep the rain out? if they sit in the bottom of the can do you find their butts get a lot of poop stuck to them?
Some pens have a roost some don't. I find my birds in some pens will not use the roosts. In my Lav pen they will not use the log to roost on or the 2x4
