This is my 2nd time buying chicks I use a heat pad above them and both times I've owned chicks atleast 1 or 2 get trampled under the heat lamp and there bodies are almost one sided due to being trampled from other chicks and for next time I want to try and prevent this should I try switching over to a heat lamp? They huddle up under there and push up against each other and sometimes get on top of each other.
