Yes, the door to the ladder and the little run underneath is open all the time, I iwll only close it if I am cleaning the coop out and they are all in the run so they cant get back up till Im done. There is just no way a critter can get to them. I have completely sealed off the coop and run from anything. It has no gaps bigger than 1/2 inch hardware mesh, and the mesh extends 2 feet from the run on all sides so nothing can dig under. Sounds like you could do with a coop like mine to live in yourself by the sounds of the driveby shootings and things.
Do you think there is a connection between Ikea and the driveby's
We don't have driveby shootings here that I know of, but we do get gypsies and the odd tealeaf (theif) that might wander around looking for scrap metal or anything not nailed down.
On closer inspection in the coop this morning, I found that there was another egg, but it had be smashed and not in the nest box. Also one of the shop bought ones had a dent in it. I hope they arent turning into egg eating chooks.
