ok here it is. i habe some cochins that are in a run and coop outside and are about oh i dont know 10 weeks old, i have a small bowl that i fill with decaying granite pieces for them for grit but every time i fill it they eat it all within an hours. so my question is, is this bad for them or do they need more? there is 4 cochins in this run and the cup is i guess about the size of a large tuna fish can only deeper like 3inches deep. they are feed starter grower right now with the occasional treat. and whatever bugs and stuff they catch in their run. thanks for your input
