Chicken dressed out weight

[PaperChicken]

Anyone have any numbers on how much a bird should dress out compared to what it weighs live? Looking for an ideal weight vs age (cost).

I have white leghorns but I'm interested in hearing other birds too. If a white leghorn cockerel weighs 4 lbs then what percentage weight does it loose after being cleaned?

I think finished weight like 60% of the live weight? But I don't remember completely

Broilers =70%
Roasters=75%
Cornish Game Hens=65%
according to this.

My scrawny, gamey birds are only 60% and most of that is bone.

Like others have already said, the ratio changes as the weight of the bird changes. And heavy cornish broilers dont follow the curve. At about 4-6pounds live weight, I've found a reliable average to be 70% for most red broilers and heavy laying stock. Lighter laying hens tend to be more like 50-60%. And closer to 75% for cornish broilers.
