Nope, that isn't molt... even though it COULD be in March as chickens do what their body tells them regardless of what we think they should be doing.
It does look like parasite or rooster damage if you have one... more like parasite... lice or maybe norther fowl mites. Easiest seen after dark with a flashlight, part the vent feathers down to the skin and look for bugs running away. On the abdomen to. Notice if the skin is red and angry or just pink flesh colored. My preference for treatment...
A simple spritz just below the vent, under each wing pit and to the nape of the neck, feathers parted so it hits the skin. Under $8, very effective, easy to use. Soaking the bird is NOT needed. No egg withdrawal required. Also available under other brand names... the effective ingredient is Permethrin.
Take this time to also check the crop.. is it hard or squishy or empty at roost time and again in the morning before feed? Sometimes excess drinking without feeding can be a blocked crop. Are dropping looking normal?
Sometimes in older birds who haven't molted their feathers can start to look ragged like that even without parasites. Note some mites are microscopic, like scaly leg mite or depluming, while others like red mites live in the crack of wood like under the roost or in stumps and only come out to feed on the birds.
Good luck!
