Do I need to increase cooking time if I stuff chicken

[Lookproperly]

I am planning to roast a big chicken. My scales are broken so I can't weigh it but the packaging suggests coming it for 1 hour 55 min.

I want to stuff the chicken though. Can anyone suggest how much additional cooking time I should allow for if I stuff it?

Thank you!

Hmm, you really need to weigh the bird once it's stuffed. I guess if you can decently estimate the stuffing weight and add on, then you can work your timing out from the total weight that way.

I don't know the answer, but you could weigh the stuffing and add the weights together.

*assuming thanyou know the weight of the unstuffed bird..

Yes.

yes. weigh the finishes product and cook according to that.
