I appreciate the info about feeding scratch. Didn't know that it raised the body temp. I mixed it in with egg crumble and corn. I'll keep doing that for now 'cause cooler weather is coming on. I also mix in food grade DE with my feed and feed only non-medicated feed. I put it in my 30 pound galvanized feeder in the chicken house. I crumble egg shells up real fine and keep a little oyster shell available. They are laying to beat the band! I have 2 roos and 9 hens. 5 cats. 1 dog!!
