There are a few schools of thought when it comes to air frying chicken. Some people believe that tying the legs together helps to ensure even cooking, while others find that it makes the chicken more challenging to turn.  There is no right or wrong answer, and ultimately it comes down to personal preference. If you do choose to tie the legs together, be sure to use kitchen twine that is heat resistant.  Otherwise, you run the risk of the twine melting and becoming stuck to the chicken.  Another option is to tuck the wings under the chicken’s body. This helps to keep them from burning while also keeping the chicken stable in the air fryer. Experiment until you find a method that works best for you.
