HElp!! Disaster!! Babies dying averyday

[the1honeycomb]

I have lost 6 chicks in the last 3 days!! they have plenty of fresh water and feed, I can only imagine they are either cold or they don't have good enough ventilation I put a heat lite in with them. gave them save a chick additive, and the door to their coop is open but I am still finding them dead!!!??? any ideas

how old are the? My guess would be they are getting too cold if you have them outside and they aren't fully feathered.

More info please. Age of chicks how is there surroundings What are you brooding them in? is it draft free? What kind of light are you using?
