When for example sampling 120 chickens each with its own unique identifier and additional information it could become a bit confusing on where to register what in the SEEK platform.

For example you can register the organism chicken as a global entity but each individual chicken currently has to be registered as a sample. Of these chickens (which are samples) actual samples are taken and registered in the platform as samples of samples.

Ideally it would be nice to have a level between Organism and Sample which would then create the following:

Chicken (Organism) > Chicken1 (Observation Unit) > Sample 1
Chicken (Organism) > Chicken1 (Observation Unit) > Sample 2
Chicken (Organism) > Chicken2 (Observation Unit) > Sample 1

I mentioned Observation Unit as I encountered this in the MIAPPE standard which describes it as followed:

Observation units are objects that are subject to instances of observation and measurement.
An observation unit comprises one or more plants, and/or their environment.
There can be pure environment observation units with no plants. Synonym: Experimental unit.

Not sure if there are better solutions but from a user perspective I think its rather confusing to have samples which are actually animals, bioreactors or other kinds of entities.
