hist-brewing: hydrometers

<<<As eggs age, the air cavity within gets bigger and so the egg starts to
float more. >>>
Now that has me thinking.  Is the shell porous enough to allow air in or
does the eggy part get denser?  There's a few more but I'll leave it at
that.  Anyone who has an answer can reply personally, as we are getting a
little off topic.
<<<If you kept your own chickens, you would know.>>>
Chickens tend to be our major/sole source of eggs nowadays, but not so in
pre-industrial times.  Pheasant, quail and other eggs were scavenged up and
sold at market so a reference to "a small egg" or especially "the smallest
egg" can most assuredly be something smaller than a chickens.
