I think it's the females who have given birth, not the 'guys' RR. ;-)
But it's also an individual living animal thing, and if one insists on a human comparison....
....some women gain extra weight when gestating, and some actually lose weight, irregardless of their consumption.
Some women can't hardly eat much at all during gestation, nausea early on (or all the way thru) and lack of internal space later on.....hahaha!
But, back to chickens.....
Not sure a chickens consumption is too much different when laying or not laying,
but they sure are slimmer when laying as they're using the consumed nutrition to produce the eggs rather than storing it as fat and/or flesh.
Butchering older hens has shown me that a laying hen has wayyy less fat on/in her body when laying than when no longer laying.
Agrees, I have also observed that they eat less during parts of molt as they 'don't feel so good'.
