My BIL mentioned LS-50 for respiratory infections. I have 77 chicks, no one is sick. There is lots of room and they will be free range when they are older. All are doing extremely well. Is this recommended by most chicken folks as a precautionary thing or only if I see there is a problem? He said you can't eat the eggs for a good while after you administer this. They are babies now, so now is the time? Will this make my chickens non-organic for the rest of their lives? We were hoping for minimal meds and chemicals in them. I know very little about LS-50. Info please!
