I **like** your old books.Much better than my books! Thank you.
I'm skimming the download now - 180 pages +/-, about 20 preface, cover, publisher, thank yous, etc. About 40 pages of reference at the end. 15 or so talking about units of measure. That leaves around 100 pages of "meat", some of which you may be able to skip as inapplicable (feed for avians other than chickens, or for chicken types you don't have). Basically, 1-2 hours of reading pleasure, and a lifetime of future reference.
