I'd also use a microwave defrost. Certainly not in hot water or cooking from frozen. You have to be very careful with chicken. If it's for tonight I'd get fish and chips.
Having just drunk a bottle of wine whilst waiting for your chicken to thaw out I think you should abandon it and join me!!! Send for a pizza and eat the chicken (thawed out overnight at room temperature) tomorrow!!! xxx
Allowing food to thaw in the fridge is not only "safer", but it also saves you money. The frozen food helps to keep your fridge cool thus saving on electricity. I realize that it's not a lot, but hey, every cent saved is a cent your pocket:)
