Hello chicken experts: I am about to get 2 ten-week old hens for my backyard. Most of this yard is chain-link fence, and I have neighbors on all sides. I am hoping that my two hens will use a finished playhouse (walls and roof) for their coop. I have a few questions that I would love to have answered: 1) If allowed in the yard freely, even with wings clipped, will these chickens easily bypass by 4' high fence? 2) What do I need to do to ensure that they will lay eggs? 3) Will they frequently try to escape the regular yard? Thanks for answering. Any info is appreciated as I am very new to this.
