So my labs (or at least one of them) has decided he likes chicken feed, and has been getting into the coupe via the chicken door. Assume that keeping them away from the coupe entirely is not an option. If my current door is somewere between 12x12 and 14x14... what dimention would you make smaller to keep them out. (yes even at 14x14 my 80lb lab is squeezeing through it. im inclined to think to make the opening smaller top to bottom, leaving a relitivly wide(ish) hole, but only 10 or so inches tall.... (hard for them to squirm under something than through something) my nest boxes are like 11x12 and the girls dont seem to mind that. When we had them in the tractor, we would let them out via lifting an end up and setting it on a block that was neary 8" tall and they managed to squeek in and out if that fine. (granted they were a fuz smaller) Im fairly shure i have a RIR and some mix of a red and buff. fairly heavy breads. I plan to add a few (3-4) buff opingtons this spring. **********short verson************** how small of a door can i have for my girls?
