The green pen is 42" across the bottom, 26 1/2" at the top and 29" tall.
The black one is 26" tall and about 23 1/2 wide. The whole yellow top either flips up or you can flip up only 12 of it, which is great for keeping flighty birds from getting out when you need to reach in for something.
The folks at Belle farm need to pay me a commission (LOL).
