' "I noticed on August 22 that seed (millet) passed through the young undigested; the trouble is 'too much food.' It 

 is necessary not only to use fine seed, but also to be very careful not to overfeed during the first week or two weeks. One 

 must keep constant watch of the droppings and cut off the seed if it passes undigested. Some soft food (bread-crumbs), 

 cuttle-fish bone, oyster-shell, charcoal, plenty of sand-grit, and some lettuce seem advisable or necessary."
