ity of an egg as every defect an egg may have

Another test is to shake the egg. Ii stale. 
the contents will run together so one can 
hear the motion in the egg. This test does 
not apply in winter months as a new laid 
egg may freeze and upon thawing out it will

Not all stale eggs, however, are bad. For 
an experiment, I took an infertile egg from 
my incubator after 10 days incubation, had 
it hard boiled. If the circumstances con- 
nected with it had not been known, I doubt 
if anyone would have called it bad, for it 
really tasted good. 
A new laid egg eaten the day of laying or 
perhaps the next day, after boiling, will show 
that it is new laid by the skin adhering to 
the shell: it will not peel easily,
