No...I read someplace, maybe here, not to use ACV, BOSS, Corn, etc in the heat because they actually increase the birds body temp...and ACV does something the weakens or reduces their calcium. They just get their frozen treats, ice in water, misting, balanced non-antibiotic commercial feed, free range several times a day (mostly a.m. and p.m. in the heat) frozen water jugs. They have oyster shell available at all times and clean, clear, cool drinking water replaced several times a day. Right now I am adding electrolytes to their water once every 3-5 days to help with heat stress.
