finishing up our external nesting box and trying to figure out if I should put in dividers. Was thinking maybe vinyl curtain dividers like I am doing on the front of the box. We have 9 chicks and built the box to have 4 individual boxes in case we get more chickens. I want to have the dividers removable so there is easy cleaning. If I should have wood ones is there a easy way to make them removable?? Or do I not have any and just the curtains in the front of the box??
