I have 3 chicks--5 wks old now--who have only had "Nature's Best Organic Feeds" chick starter/grower that I get from Tractor Supply. It comes in a crumble form and for the first 3-4 wks I ran it through a food processor (pulse 5x) to break it up a bit. Their brooder is a tent with shredded paper (think hamster bedding) and there is a heck of a lot of food scattered around. Waste, really, because they just don't seem to eat the larger pieces. Also--I"m not sure the stuff I'm buying is all that fresh. There's no expiration date, just a printed code (batch #?)--but it's listed as 20% protein on the label, whereas the website says the protein level is 18%. I can't find a local feed mill, and with so few chicks (will have a total of 6) I'd rather buy small batches. Mash feed doesn't seem to be available at TSC. Any suggestions?
