There are reports of 279 cases of salmonella in 40 states this year alone being attributed atm to backyard chickens. Good luck with your kitchen, but please do a couple things to keep it safe. Wear gloves and shoes specially designated for the chicken areas that come off before you enter the kitchen area. Have hand sanitizer at the door and use it. Have a pair of shoes you wear in the kitchen that never go into the chicken area. You may need a small mudroom between the two for this.
