I'm getting ready to go to TSC to buy some supplies in the next hour or so, and I need to buy lime. Here is the situation--I had diseased chickens this fall, which have been gone for many months. The coop is cleaned out and bleached. The run is still lined with the old sand, and I plan on getting as much out as possible. I was told it would be a good idea to lime the ground of the run then put clean sand on top. The new chickens are going into the coop today, just four of them, and I'm afraid they will be able to get into the run because the pop door can be pushed out from inside the coop. I want them to have run access if possible anyway, because it's no fun being cooped up in a 4x4 coop 24/7! So the problem..TSC has two kinds of lime. One is a powder for gardening and the other is pellet lime. (This is what the guy on the phone told me.) Which should I buy? Is it ok to put it on the ground then put the sand several inches deep right on top? Can the chooks go out there right away? I can't find any good information on using lime around chickens, everything is conflicting. Another question--my diseased birds were out in my yard free ranging this past summer. Can I sprinkle lime around my yard? Does it hurt the grass? Should I just not let my new birds free range at all? (That will be hard, I love letting them out to roam...) My other birds had avian leukosis, cocci, and IC. I got them from a bad lying farmer. My new chicks have not been exposed to anything, they are perfectly healthy so far and have been in my garage, which I coated and scrubbed in bleach before they went out there... Any thoughts? Mainly, I need to be sure I buy the right kind of lime!
