I personally think that you have too many birds in your cardboard box at one time. By looking into the box, it seems that there is alot of available space, but the main problem is that when they huddle in the light source, the stronger chicks will climb to the top and the weaker ones will be on the bottom and literally get trampled. This will make them look lethargic and wobble weakly around and then refuse to eat or drink. I don't even like to have twenty-five at one time in the same area because you will have the same thing occur. The smaller the group, the less chance of smothering. You might try to separate the box into sections and put twenty in each section.
Several years ago I visited poultry houses that raised for Tyson Foods and there were chicks dead everywhere that were trampled. My friend who owned these facilities said they they expect to loose 10%. Measure your losses based on those percentages and see how far off you are, if any. I think everything else you are doing is in line with successful expectations.
I myself, recently got a shipment of 30 chicks in and have lost 5, but they were on the road for three days........I received them on the 4th day which was too long. The longer in transit, the more losses can be expected.
Best of success!
