No we do not recommend you cook a whole chicken in the Halo. 1. The only whole chicken to fit in realistically would be a baby chicken ( a Poussin) even then it would be a squeeze with the centre hub. 2. A whole chicken would need to be portioned up and the skin removed 3. Chicken skin is very fatty and would give off a lot of smoke. In the IB we do not recommend cooking very fatty products, eg poor quality sausages, lamb chops, chicken with the skin on
