Is there any reason why I can't make my own oystershell grit?
The last 5kg bag of "oystershell grit" that I bought turned out to be about 4.5kg grit & only 0.5kg oystershell. The hens peck out the tiny amount of oystershell & leave most of the grit behind, as they've got plenty of that available already. So, living close to the North Kent coast which is littered with oyster shells, I wondered if I can add extra oystershell to the grit that I have.
I guess I'd need to start by washing the shells in soapy water & then boiling them in clean water to remove any risk of bird flu. When they've cooled, do I simply smash them up with a lumphammer?
Could the pieces be too sharp? Should I just try it & see? Have any of you done this yourselves?
