OK, so I have read many differing opinions on grit for chicks. Do I or do I not give them grit? I did pick up some special chick grit today at the feed mill - do I sprinkle it on their food? Or how do I give it to them? I read somewhere that once they start scratching you should give it to them. Well, mine are scratching the heck out of their woodchips... Also, they are 8 days old now - what should the temp be in the brooder? They seem very content - not huddled together or smashed up against the edge of the wall - they play around, digging at the wood chips, etc. and eating like mad. But I just want to make sure the temp is OK.
