Restrictions on the use of table and restaurant scraps must have made a
difference to the nutrients available, compared with the "old days" when
chooks were like compost heaps - you put your spare edibles into the
chooks and got eggs & chicken meat. In the days before supermarket meat
in neat little cuts on plastic trays there was all the waste meat left
on the bones, yum yum yum from the chooks' point of view.
Even so my parents had a tin of "meat meal" which got added to the feed
sometimes. Don't ask me when or why: that was of no interest to me at
the time.
I'd be surprised if many chooks, household chooks anyway, lived on
grain. They were like the pig, low-cost producers converting unwanted
stuff to valuable food. Well, that's what I knew in New Zealand when I
was growing up. Things have changed a lot since then. Battery farming
for instance. May the gods rot those who profit from it, starting at
the toenails & dandruff and working steadily till the rot meets in the
middle.
