It could be you've gotten some wrong recommendations, or just have had bad luck. You said you switched from a plastic to a metal container just like the store, and that you've made sure the temperature is 90-100. How do the chicks behave when they have been in the container a few hours - meaning, are they eating, drinking, then sleeping, and if sleeping are they piled up together or all spread out at the very edge of the container or the edge of where the heat lamp is most intense? What food and bedding were recommended? Are you using a bulb with a coating on it to prevent breakage (these off-gas something that kills birds)? Are you adding anything to their water?
