Hello, I'm new to chickens, and in the middle of my coop/run build. I have 5 chickens, still indoors in a brooder. My coop/run is 6 x 20, with the coop taking the 5 feet of one end (so a 6 x 5 coop). I'm in MN, so I am going to insulate the coop, and want to keep the nesting boxes internal to the coop for warmth and to prevent eggs from freezing, but I also want to be able to collect the eggs from outside of the coop, via an egg door, without entering the run. Am I right to be concerned about the chickens escaping out of the egg door when I open it to collect eggs? Because if they did, they would be out in the unfenced yard, the street, etc. Are there any design parameters I should use when constructing the egg doors/nesting boxes to prevent this, or do chickens generally not try to escape the coop/nesting box during egg collection? Thanks!
