Just keep in mind that you will want to do 2 coats of Black Jack (just 1 coat is a little patchy). I think I only waited 3 days between coats, so it was still slightly tacky when stepped on, and the chickens were probably in about 10 days after that.
Yep, I did 2 coats as well. My humidity at the time was about 60% and hi temps were about 70, I was able to do the second coat in 24 hrs. It was slightly tacky but not bad, nothing stuck to my shoes or me. I put my bedding and chicks in about 7 - 10 days later.
