I'm starting on a new coop for my Welsummer chicks arriving in the Spring. Once they start laying I want to keep records of the eggs that each hen lays, color, etc. I have heard of one way nesting boxes so the hen can't get out once she lays her egg. This will give me a chance to record what each hen produces. I have gone thru many pictures on the "Coop Design" page and didn't find any pictures of what I am looking for. If any one has this set up and can post some pictures, I would appreciate it very much. Any other suggestions of how to keep track of what each hen produces would be appreciated as well. BTW, I am not going to sit and wait on each hen to do her business and then see what she has done. 
Thanks in advance.

Thanks in advance.
