How old is she? Can you post a picture so we can see the beak? How is her weight?
She may just really crave snails.

If she's on a good balanced feed and her weight is good, then she's probably fine. Depending on how the beak looks, a trim might help her feed better, birds with this issue sometimes can't hone it sufficiently on their own and having it get overgrown just makes things even harder for them. Feeding her a mash regularly in an open, raised, deeper dish, can make it easier for her, dry crumbles or pellets are a lot harder for birds like this to pick up, and anything ground level is harder.
There are poultry vitamins available that you can mix into the feed. Rooster booster makes one.
She is just under a year old! I will post a picture of her beak in a few, but we have been able to manage it well. Weight wise she is very skinny. Feeling her sternum (or what ever it is called in birds), I would give her a 1.5 or a 2. I can post a picture of the scale I'm looking at if need be.
I try to do everything I can to give her as much feed as I can, feeding her 3-5+ times a day.
We had an incident when we first tried to trim her beak, she bled and we couldn't stop it. I would say she almost didn't make it. Ever since we have been weary of trimming her beak and have tried to file it down. However, she has been good about keeping her beak down as well, making our job easier.
Better yet, leave the honey and garlic out. Is she thin, by feel? It's hard for her to eat enough to also be producing eggs, and she needs lots of help, as you've been doing.
Make sure she doesn't have mites or lice (look at night with a flashlight), And maybe have a fecal run looking for intestinal parasites. Any added issues she has will make her life even more difficult.
Can she pick up grit and oyster shell? She might need both, and have problems getting anything off the ground. Do you have deep dishes of both in your coop?
Are her egg shells hard, or thinning out/ That's a clue about her calcium needs.
If she is underweight, she's just not able to eat enough to meet her needs, often what happens with these birds.

She is underweight, and I have done everything I can to try and help her grow and be healthy. Like I said, I would give her a 1.5-2. I don't think she has any mites or lice, but I will check again today to make sure.
She isn't able to pick up anything that isn't in a sticky mash form. I have seen her peck at an egg shell for 5 minutes straight without success (hence why we are giving her layer feed). Even when we put the egg shell on top of her mash feed, she would try to peck the shell with no success (if only she new to eat the food!!!). We used to pulverize egg shells and mix a few pinches into her food each time we made it. I have started to do that again, adding it into the layer mash. I also added some grit to her food as well, mixed in so she wouldn't know.
She is the smallest bird in the flock, and I know it has got to be hard on her.
Last night, after giving her more egg shells, she didn't rush out to the same spot of earth, and hanged around with the flock. So I am pretty sure she just needed the calcium.
Regardless, I need to get her on some vitamins!
