I was told to give my 1 month old chicks grit and so I’ve ordered grit online but when it arrived this is what happened the lable says to not give it to baby chickens and I have not old chickens + I couldn’t find the grit you guys are talking about I also went to the feed store near me and the gave me shell grit and I was told it has calcium in it too so I’m guessing that’s not good for them too? Can someone please show me a picture or guide me of what grit I’m supposed to give them!
