Summer Molt?

[BansheeBenji]

I have a weird thing going on with one of my chickens, Queenie. She seems to be molting; her butt feathers are looking kind of loose and she has lost some. She just turned 16 months old, and is a Salmon Favorelle mix (my guess is part bantam because she's so little). She's vaccinated, and was wormed in January.
When I gave her a bath I checked her all over for mites just in case. I do dust them and use a combination of a spray, de, and herbs in their coup. I've never had issues in the past. I've made sure to give her a little extra protein in case she needs it, and they have oyster shells available at all times. She was very broody for a few days in April but not since.
She's eating/drinking/laying just fine. Her color is normal. She is at the bottom of the pecking order, and they do pick on her some, but I've never seen any evidence of feather picking. She's been a little more reclusive lately, but she's also very temperamental (read: slightly psycho) and likes her personal space. But as soon as she thinks I have something, she's up and playing bumper cars with the flock.
Everyone else looks totally fine. I'm really thinking that she's having a little molt because she didn't molt last fall/winter. I can see new feathers growing back in. Does anyone else have chickens with weirdly timed molts like this?

Yes, it happens. While they generally molt in late summer or fall it can happen any time. I have one that molts very early every single spring, she's almost done this year. You will often hear of birds molting in the dead of winter when it's really cold. Stress or illness can trigger a molt, but it can happen for no recognizable reason at all, just whenever their bodies say it's time. Since you see new feather's then that is likely what it is. It can be a hard molt where they look practically bald, or a soft molt which is hard to notice, or anything in between. As long as everything else seems OK, I would just keep an eye on her. They will often keep more to themselves since new feathers coming in can be sensitive and they don't like to be handled much.
