We made this today for our newly hatched BCM's. It is 2 ft high, 2 ft deep and 4 ft long. Will be making a box double for when they get older and use this one for the next hatch. The top has hinges in the back and two hooks in the front to keep unwanted critters out of it when we carry it to the barn tomorrow. It gets to stay inside tonight, the granddaughters want to play with the chicks tonight. First one so we're kind of proud of it.
