Hubby got me 3 chicks this past Tuesday.. This morning he told be to start figuring out how to do their nesting box (s) and roost. I have a raised pen with singled roof that is about 4 ft wide by 6 foot long.. It has two front doors.. all sides are covered in hard ware cloth... How can I fix it up for when the girls are ready to live in it.. They will free range part of the day.. This was my first duck pen I housed my two Black bellied whistling ducks in it until they Flew off two years ago.. At least one of them got a boy friend and left.. the chicks are rohde island reds and new hampshire red..
