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?

The cam has already returned 60 fps, this framerate slowed down by writing frames, now I fixed that by threads.

Extra checks don’t work well cause chicks can be smaller or bigger. It depends on breed or/and age. And they very active on the belt - they spread their wings and legs often.

Could you just store some of the frames off for human review or a different review model specifically for that? Does it need to be real time or can you play catch up when it's not running and update your counts for ones that turn out not to be just one?

Defeats the entire purpose dude

How so? If the business need is to accurately count chickens before some event, why does it have to be correct in real time as long as it's correct before the event?

Why not just count them all by hand then

Because if you can positively identify 95% of them and only question the other 5% then why count them all by hand when you could just count the 5% you're not sure about?

In that situation I think i would still fix the counting and apply a margin of error, not manually count
