Does a chicken egg weigh the same when its laid and when it hatches?
Answers:
I think it is heavier when it is freshly laid.
Its slightly heavier when first laid.when ready to hatch the shell is thiner and thus weights less.
You'd think it would have to, but for some reason I suspect it really must be lighter when it hatches. Sure the chick is eating and using energy, but to make more chick. Nothing is entering or exiting the shell (or is gas entering exiting?) I have no idea but very interesting food for thought. Thumps up on the question if I was allowed.
If the egg shell was completely non-porous the total total amount of matter inside would be unchanged as the embio developed into a chick, but this is not the case.
Eggshells are soft when laid and slightly porous, even when they have hardened. There is a certain amount of evaporation and gas loss during the incubation, so the egg weighs less when hatched than when it was laid.
But which came first?
no, the chicken is growing inside the egg, at first its the size of a grain of salt
no it doesn't..it varies and in some cases the yolk content increases and the water content is absorbed.it also depends on the hatching environment and the bred ding cater gory.
Yes, it would weigh the same. The law of conservation of matter says that in any chemical reaction (yolk turning into a bird), matte will be conserved. The only thing that changes would be what the matter in the egg is.
no
