First Saturday Lime vs. Ag lime

I layer barn lime > horse pellets > pine shavings to keep things dry and from getting too smelly.

From the First Saturday Lime website, their product is a combo of hydrated lime & citric acid that has been neutralized from giving a dangerous chemical reaction. But they don't exactly explain why it's better than barn lime, just that it's 'stronger'.

I would give the regular barn lime a try first - 50lb for $3.29 (TSC) vs. 20lbs of FSL for $30 (Amazon).
I got lucky and a Home Depot was clearing out FSL for 3.70 a 20lb bag, bought all 6 they had. Not sure why they were clearing them out because all the other stores were regular price 37.00
 
Barn lime is (generally) Calcium Carbonite. Basically ground limestone powder. Ag Lime is usually Dolomitic Lime, which is mostly Dolomite, essentially a bunch of calcium carbonite bound to some magnesium.

Quicklime is Calcium Oxide.

Each has their uses. Very little overlap. But more overlap between Barn Lime (fast) and Ag Lime (slow) for acid neutralization than "Quicklime", used primarily for concrete and some industrial processes (like steel manufacture).

"First Saturday Lime" is Calcite (a calcium carbonate form) plus a small amount of citric acid.

Hope that helps.
 
New Chicken Mama here! I have moved my 13 chickens into their coop last week and they are doing great! The coop has no floor and is just on the ground. I have put a good thick layer of pine shavings down, but I am wondering if I need to add lime. Of course I have seen the ads for First Saturday Lime, but how is it different than regular Ag Lime? I am terrified of mites or lice infestation and want to make sure I take the proper measures to keep it from happening. I live in Central Mississippi and we have had a VERY wet and rainy spring so the ground is staying wet. I added more shavings to help with the moisture. Any tips or advice is appreciated!
I am planning on using barn lime and DE. The other is just too darn expensive!
