Sarah, I am in the same situation as you. Our vet dermatologist prescribed RC Hypoallergenic Soy because one of my girls is reacting to chicken, turkey and tapioca (and I am sure there will be more). I had ordered a bag of Wellness Simple Salmon prior, so I am trying that first. I have not completed the transition yet, but there seems to be improvement already. If she still has food reactions after 4 to 6 weeks, then I am going to the RC food to do a real elimination diet.
If you suspect chicken is a problem, you may want to try what the dermatologist had me do first. Take the first 5 ingredients of the food you are feeding now and increase each one individually to see if there is a noticeable reaction. I added 1 ounce of turkey to Lucy’s morning and evening meals, and by the end of the second day her scratching increased significantly. Then, after a couple of days of being off the increased turkey, her scratching calmed down.
Good luck with the choice you make.
