Could you possibly raise the door so that they goats cannot get into it? If you raised it say, 4ft off the ground and then built a chicken ladder on the outside, the chickens go in and out as they please, but the goats would not be able to climb the ladder up to it.

Goats are like weasels! They maneuver around to get where they want. They are also very strong, even little ones! Mine is about 42 pounds. She snaps 100# dog cables quite frequently.
I have a fat pygmy that can easily squeeze under a fence if it is more than 6inches off the ground...
