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!
