First, please see attached video. Several weeks ago our white brahma started making noise. Now she does it ALL DAY, EVERY DAY. Even at night! It's gotten hot now in Houston, so some of our chickens have started panting with their mouths open (see Orpington behind tree). Is this normal? All hens have dust bath areas with DE, plenty of water, a balanced diet, and plenty of shade/space. They were de-wormed using wazine a month and a half ago. I have no idea why my brahma is making this incessant noise! If it's an indication that she's sick, I want to fix it. If she's just being awful, then I'm giving her away. Please, we need help. This is driving us crazy!
