I have goslings in Tri-reo (stereo in threes) peeping, all day and starting at 5:00 A.M. They are cute though! Here is the play pen I made today from expandable screens, hinges and a hasp. It took about 20 minutes to assemble. I added a drop cloth bottom made from plastic sheeting fastened with cloths pins, a towel and bunny and a heating pad on the side. Dog is extra, poor thing and is beside herself to protect them. Cost was $38.00, and it collapses for storage. It will adjust from 21" to 37" on all sides, so you can get many configurations, and it's 18" high. I will only use this while I'm in the room due to other animals. I think I'll buy two more of the screens and figure a way to make a top that is also adjustable, probably with elastic and velcro fasteners, and hooks and eyes to secure it. My husband will be impressed. I hope!
