How much ventilation is too much for coop?

[RoyalChick]

No, I think its a great idea, and it didn't even occur to me!

I found a guy on facebook locally with $3 milk crates. I messaged him to pick up a couple, they will make fantastic nesting boxes for outside of the coop area.

Perfect!

I'll do something like this

with some milk crates on the wall.

Love that. But a word of caution. Chickens are contrarian creatures and may decide they prefer their milk crates just sitting on the ground with the top open. Others may decide they like something else.
Mine have dishwashing tubs inside a repurposed kitchen cabinet.
I nearly abandoned that idea because they are way smaller than all the advice given says they should be, but even my big ladies like squishing themselves in there and when I created an option with more space and headroom they looked at me like I had lost my tiny little mind!
