My first flock of chicks is doing very well, at about eight weeks now. I had them on chick starter, but my local feed store didn't have a specialty grower or developer food, so I mail ordered some organic developer which was fine, but absurdly expensive with shipping costs. My local feed store recommended an "all age" mash, which is 16.6% protein, 4% fat, 3.8% fiber, 13% ash. It's about 75% cheaper than the mail order developer. Is this OK for pullets until they start laying (this, plus a few kitchen scraps), or should I keep mail ordering the specialty feed? Advice?
