So far Emergency & Desease thread hasn't told me anything just asked if it was hard or squishy. It's squishy.
I'm going to keep an eye on Mable the next few days and see if it changes. She's been fighting a lot lately with my Top hen Penelope so maybe she got hurt from that. I'm glad no one is alarmed by it. I love my ladies, she stayed in last night I had to give her a bath cause the back of her comb had a chunk missing she's white so the blood splatter everywhere wasn't pretty. But it amazed me how long it takes to blow dry a chicken, I got her almost all dry but her down feathers were still a little damp, it's cold her at night in Ohio I didn't want her to get sick, so my first time having one of my girls spend the night inside.
