I went to Tractor Supply and picked up a bag of chicken grit, and a bag of DuMor 24% meat bird feed. I planned to supplement the 18% feed they've been getting with a little of the higher protein feed each day. In the store the 10 pound bag wasn't loose, the feed was all clumped together. Got it home and opened it up and the feed felt slightly moist, and smelled bad. I don't know if it's mold or what, but I'm not giving it to my birds. I'll take it back and get a refund.
Also picked up three 2x6x10' boards (70% off cull lumber) to use around the base of the chicken run I'm building. With the other boards I have the base will be close to 12" high, so it should be good for deep litter.
I got a 25# bag of grit, but it's chicken size, not chick size. I'll break it up with a hammer, and sort or sift out the large particles for now, until the chicks get a little older.
I'm pretty disappointed about the feed being bad.
Clumpy feed has aways got wet. It's a botulism risk. I learned that the hard way when moisture got into my scratch. Leak in awning and water made it's way in where the lid handle attaches. Birds were suffering before I even saw the actual mold. Main reason I don't dump the feed out of the bags anymore. They are another protective layer in the metal trash can.
Yes take it back for a refund. I've seen some places leave feed pallets in the rain. The bags are only water resistant.
