Jersey's are SOOOOO busy.
The first shot of the hen who has come up for air, I'm so happy to see that. My Jersey Giant has lost all her feathers under her wattles too. And I only have the one JG so I never know what's normal or not w/ them. I'm not sure if she's starting to molt or I was afraid she'd rubbed off all her feathers on something. But given your hens looks exactly the same, maybe it's a JG thing.
She did and UGLY molt last year and I was curious if she'd do that again this year, if that was now her way of molting, or if she'd do a more controlled molt. I was wondering if the no feathers under the wattles was the start of the molt.
