Trampling chicks

[taylacline]

I got 6 chicks about a week ago. 2 I got were a little older but Rural King told me I shouldn't have any issues putting them all in the same brooder. Well now 2 of my smallest chicks have been trampled by the larger ones. Im afraid it'll happen to my last 2 smaller ones. Is there any way to prevent the trampling? This large chick is probably 3 times bigger than the smallest one now

I would probably divide the living area with hardware cloth. This way they can still grow up together, but they won't hurt eachother. And yea, when they hit like 3-4 weeks, they tend to get pretty wild with jumping, flying and slamming into eachother. Not a big deal if they are all the same size, but I could see that being dangerous for very little ones.
