Hey there Jesse, you have been busy.
Great photo of your new babies. You will need a lot more top dressing around and under the rosettes to keep the leaves off of the soil. During wet cold weather the soil can encourage rot.
I'm with BigT on that potted semp. WOW!! You really got your money's worth with that one.
I get my chicken grit, same as what BigT gets, from my local feed stone. $10 per 50lb bag.
