No Grendles on your ship
There is a limited amount of creatures that can be on one ship so if you have a whole bunch of Norns there won't be so many Grendles. If you have reached the limit some of your eggs won't hatch until another creature dies.

Hidden song
Play the "DJ_G.wav" file in the game's sound directory to hear a hidden rap song from Grendel.

No more Grendels
Don't want Grendels? here is what you do. Take two grendel eggs and throw them in the the pirhana pit( press green button at the end of the grendel home) See, the game only allows two grendels to live in the spaceship at a time, and if there are two grendels eggs in the pirhana pit, The mother grendel thinks there are two grendels walking around. Also unlike every other living thing when dropped in the pirhana pit is devoured by the pirhanas, the pirhanas never touch the eggs. P.S the pirhana cage is at the very bottom right of the grendel home and the grendel eggs appear very close to the pirhana cage (right where this yellowish orange hole is.) You can also do this with ettins. Guaranteed to work if done correctly. Oh, and I had about 16 norns alive and there were still only two grendel eggs that were laid. far as I know those grendel eggs are still there:)
