no idea what "Jumang Star" is so i can't help with that.
i understand the agricultural pack needs eggs, you can still get egg's within a 40 chunk radius of spawn at a normal quality which is "huge", if you automate breeding of the normal eggs you should never encounter an issue. You can also use the quality eggs to make quality packs much easier which actually makes the creation of science easier as agricultural packs are the most benefited to making with quality as you can also breed quality bacteria for quality ores which simplifies the process.
This issue was considered when making the mod. If you make a base > 40 chunks in each direction and can no longer get normal eggs and you don't have an automated breeding loop and also can't handle quality eggs for quality packs. I would suggest disabling quality as you aren't using it.
Something ill add to the TODO list is handling regenerating bases on load if quality is disabled / enabled so you can freely change what you are trying to do.
