congratulations!! Welcome to the world of chickens. I swear It's a gateway drug to other livestock pets. My daughter is begging for pygmy goats now.
The grit won't hurt them at all I sprinkle some in the bottom of the brooder for them to find when they scratch around. I have a thermometer in mine but could never get that 95 perfect the first week. Plus they never wanted anything to do with that much heat. this is my 3rd round of babies now and they are all around 80 in the warmest zone at 1 and 2 weeks. I adjusted a lot at first if they looked cold or too warm. I also keep my bathroom door closed and they are in the brooder in there. It's pretty warm in there most of the time so I think the temp is consistent for them. Not saying that you should do that, just saying that you should use the guidelines and monitor what works best for your birds. A thermometer is about $2-4 at the pet or feed store.
