Several weeks ago, my two- and four-year-olds got in to the Purina Layena feed and wasted a ton playing with it. I cannot buy it here (my husband picked it up for me when he had to travel for a work conference), so, needing something to feed them, I bought some Payback Poultry layer egg feed from a local source (20%protein). Apparently, it is meant to be mixed with equal amounts of scratch feed and fed to chickens, but I gave it to my quail straight. I was worried that their egg production would drop off, and it wasn't doing so great as things were--average about 3 eggs per day from five hens. To my surprise, they now produce five or occasionally four eggs per day, and the eggs have gone from an average 9 or 10g up to 12 or 13g. The protein is the same, so I wonder if the cause is some nutrients being more concentrated in this feed that is meant to be diluted? It's a pleasant change all around, since I can buy this feed here in town for ~$7 less than the layena per bag.
