Thanks for the reply,, I knew I was grasping with the VetRX , however I felt it couldn't hurt ,, Purina Electrolytes & Probiotics in their water , medicated chick starter,, cleaned their coop / brooder , fresh shavings , observed droppings of 1, theres 3 looking droopy , 16 total , lamp is angled to 1 corner, heighth is adjusted , 95 in a roughly 18in pattern, draft free garage , unplugging light when temp in the garage is above 80,say 85,, 13 are doing phenomenal , 3 are humped up , losing weight , eating less !! Should I try Corid & isolate the 3 ?
