Possible Nest Boxes?

[ci_cyfarth]

My flock is 11 weeks old, so I'm starting to look for possible nest box options. I spotted these this week and picked a couple up, but was hoping some folks with more experience could give me a second set of eyes.

Current flock is four birds: one White Leghorn, one California Can, and two TSC Blue-Legged Beauties. Pic with 12oz cans for scale, dimensions are 9"x8.5"x5".

Box recommendations are 12x12 inches for the average hen. Those are also lacking a front lip, and eggs and bedding will roll out.

They've got a bit of a lip -- hard to see at that angle -- but this is exactly the feedback I needed re: size. I'll return them and find something a little bigger.

Thank you!
