We have 8 chickens who are about 14 wks old (bought them at about 1 - 2 wks), and they are barely eating their food. I still have them on start & grow feed because of their age and put about 4 lbs (I use a 2 lb Folgers coffee can) in their feeder every afternoon after I get home from work. The next day I dump back about 3 lbs, mix it with fresh feed, and fill it again. We live in central North Carolina and right now our temperature has been running in the mid to upper 90's with a high heat index. Could the high heat be causing them not to eat as much? Or should I start them on laying feed and just mix it in with the rest of their starter feed? I am making sure they have plenty of cool water to drink.
