The skin you see under it's wing is normal, even as an adult they'll have a "bald" spot under their wing. I still recommend stopping all treats, including the mealworms (orange poop) with is extra protein which can cause softer poop. All chicks at this age needs are warmth, a clean environment and their chick starter. I use medicated the first month then switch to Flock Raiser which I ferment. If you want to continue vitamins fine but I prefer no supplements as their feed is balanced and all the nutrition they require.
You state the Legbar is loosing weight, is it being kept from the food? Bullied? Do you see it eating/drinking/pooping? Is it active? Smaller than the rest? Did you get it from a hatchery? Breeder? Hatched?
