How to start biter egg production?

I don't know where to start, do i find a nest first? Can i move it after capturing it ? Can not find a simple biteregg blueprint, do i really have to ship bioflux from gleba forever? And how i make fish production to sustain the nutrition? All the guides are super complicated and my little brain is tired. I just need the soils fast to increase production because gleba stompers are beating my ass.
