There's nothing wrong with wet feed.
It’s true most chickens eat their feed just fine dry. And in a case like yours I’d offer both.
Some chicken keepers ferment their feed for nutrition purposes.
And some for other reasons. Examples: cold weather treat, beak injury, tempting a sick or injured bird to eat, trying to get a bird to take in more hydration...
people like me occasionally offer “mash” just because!
I don’t even let mine soak.
I literally pour warm water straight from the tap over a bowl of plain dry chicken crumble.
By the time I walk from my kitchen sink to the coop, it’s absorbed all of it.
No fuss, no muss, but somehow my chickens act as if I’ve TOILED over it. And if I toss on a dollop of plain no fat yogurt.....
I’M A ROCKSTAR!
Eating by means of little bits of food takes a lot of pecks! And chickens peck hard.
A wet mash is just easier to eat for an animal with a mouth issue and has the secondary benefit of ensuring hydration. Like picking up a whole glob of mashed potatoes vs, one piece of crumble at a time.
More food per mouthful.
This bird has a split bottom beak. The bottom beak acts as a ladle when they drink.
So one might say she’s equipped with her own dribble cup.
IMHO, Wet food would just be something to consider if you feel she needs a boost, has a sharp keel bone, is lighter than the others, or suffering in the heat. It would help solve any shortcomings in both these areas.
Listen, she’s made it this long eating who-knows-what, so none of what I’ve said is a directive!
We just all love to make suggestions!
I give mine wet feed daily. I make mine "fresh" too (no fermenting) - I either soak it overnight or for an hour or so in the morning.
My birds love wet feed.
They also have dry feed available free choice.
