Hiya folks. Any notes on nesting boxes? I was just told that they get pretty messy inside and if we are using wood, make them removable and paint the insides for easier cleaning. I have also heard that the plastic bucket or milk crate ones could work as well - but what has been your experience with what is easy to clean or not?? Any trouble shooting tips? Thanks a bunch!!! p.s. I will ask in the egg layers section as well.
