Hello All!! My chickens are currently 14 1/2 weeks old, and I've been noticing that my Buff Orpington and Silver Laced Wyandotte's faces turn from red to pale, or pale to red, and it happens within minutes. It is hot here in Florida, but they have plenty of shade and water. Is this anything to be worried about? They seem to be very happy and healthy chickens. These pictures were taken within minutes of each other. There is a much bigger difference than what's shown in these pictures, that show better when the pictures are larger (or in person): Thanks!
