Silver Jeep, post what you are encountering in another thread. You're post got lost in the fun we were having with feather sexing. Also, put it in diseases, chicks should not smell. This does not sound right at all.
Be prepared, age, where they came from, what you're feeding them, where they're kept, what do their droppings look like, are they drinking a lot but eating very little. Give all of that info when you post it.
