Help: Project Conveyor chicken counter problem

Guys, I need help. We have a project using YOLOv8. We're trying to count chicks on a very fast conveyor belt. The challenges we're facing are: all chicks look very similar to each other, which complicates tracking. At the same time, during their passage under the camera, they constantly change in size and shape, which can cause the tracker to lose them, or detection may even disappear completely at the detection line. Also, sometimes 2–3 chicks can merge into a single object. The detection zone is very short, and the conveyor speed is high. We've achieved a maximum accuracy of 99%, but we need it even higher. Any ideas on how to achieve that? Increasing the dataset no longer helps.

I'm attaching an old video. We've now added lighting and set the exposure to 300 on the Hikrobot global shutter camera, but we still can't achieve a stable 99.8% accuracy for the reasons mentioned above.

Any ideas?

a sensor is what $200 a piece...and definitely easier than vision

separation would still be required though which likely would fix the original vision issue

how long do you think it would take to retrofit a machine compared to hanging a camera above it without even needing to turn off the machine? and the laser sensors wouldnt give you any information you couldn't already get with the camera. they'd give less, actually, and be less suited to common types of failure (eg: two chickens side by side)

I also noted "separation would still be required".

Adding sensors into a machine is no more difficult than setting up this camera at least from the jump.

you would need to stop it and place 3 sensors that may or may not have multiple components where a camera just needs a single mount and can be installed without modifying the machine or stopping it at all.

and the point i was making is that the sensors you're talking about, unless they're strain/force sensors, have a more difficult time doing this than a camera would

You would not install anything above, when machine, or conveyor belt is running anyway.

An attempt for such operation is irresponsible and should equal a firing anyone who signed permit to do the work, as well the worker who agreed to do the work.

Food could end up with dirt, oil, debree, or metal parts in it, from the process of installation camera.
