Clementine is the sweet delaware you see here. She is young and healthy and has only been laying for about 6 weeks. She is my most vocal hen, squawks up a storm at us. Yesterday she was less vocal...nobody got verbally assaulted when they were in the yard. This morning I noticed a faint whistling when she clucks. Every time she clucks. She seems fine and eating and trying to escape the coop as normal. I felt around her throat area, but I don't know what I'm doing. It felt chickeny to me. Anybody had a whistling chicken before? Could she be hoarse from being such a loud mouth?
