Having read a lot of different advice on feeding grit and/or cuttlefish to parrots (Africans in particular) it seems that even the professionals can't agree so I was wondering what the feelings are here, any thoughts much appreciated.

 Cuttlefish is OK to give if your bird will bother with it - Many of mine dont.  But grit is a no-no, it can stick in the crop and cause an impacted crop, not good 

Hope it's going OK with the little fella
