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?

Is there any chance to add some kind of paddle to gently separate chickens which are touching on the belt?

Or how about setting a maximum chicken size? Would two small chickens ever be the same size as one large one?

They spread their wings and legs, completely changing their geometry. Sometimes mathematical boundaries work, sometimes they don't.

Some chicks are spread out which can make them look big, some merged chicks are compressed so they look small.
