Calories in 4oz chicken?

Hello! So I’m in a calorie deficit right now as the first step to losing weight, and would like to make sure I’m writing in the correct amount on fitness pal.

When I google it though, all different websites give entirely different calories for 4oz boneless skinless chicken breast. It’s literally just plain chicken, nothing fancy, cooked in a slow cooker.

Can someone help? Lol thank you!
