Chicks Dieing & cant walk properly! Help!

[mooSa]

This morning i went down to check on themm like i do every morning. 5 chicks are dead and there are like 10 others that can't walk well. They all have the same problem. The first one that died out of them couldnt walk well. They are all healthy and i feed them wheat and clean water at all times. The 10 that are stil alive are sitting down. What could this be?

And they are about 12-15 days.

Are you feeding them starter food? Do they have a heat source? I've read you can give baby vitamins without iron and electrolites in the water

what bedding are you using?
what temp do you keep them at?

describe the droppings..in detail....color and consistency.
any red in the droppings?

they need to be on chick starter feed..
why are you giving them wheat?

check the crops..

I am so sorry. Are their vents clean?? Pasty vents will kill them.
Be sure they all can drink and eat by showing them the water and food.
Tell us how old they are and how long you have them.

I took them to the vet and he checked if they had any diseases. Nothing! and no their vents are all clean. I figured out some of the reasons could be that i didnt use enough bedding. i put like 1 cm of bedding, i was told to put 3 cm. But more importantly the ventilation id say is the problem and the heating. The gas heater is another problem and i kept the room closed 1 day with no ventilation. so they probably got stressed or they lack vitamins or somthing.... i mean all i feed them is wheat but im trying to make my own mixture.
