Live weight to processed weight question

[Linda in San Diego]

My DH asked me the other day about the weight of a live chicken and how it compares to the processed weight. NOT that the Delightful Dozen have anything to worry about for a long time to come, but it was a question I had no clue about and I was sure someone here would have some possible answers.
I tell DH how awesome this board is!!

You can expect the processed weight to be about 70-75% of the live weight for your standard broiler/meat chicken.

it always seems to be a lb for me no matter what size it is fryer or roaster.

Thanks for the answers. But what if the birds are not meat birds but just heavies like our birds. If a hen weighs in at 5.5 lbs, what might I expect the processed weight be?
We had steeled ourselves to process if any of the Delightful Dozen turned out to be roosters - thankfully, all are pullets so we don't have to think about that yet.
Again, thanks for any information.
