Same here for the brooder. My chicks are expected to hatch around the 8th of March. I start off with puppy pads for a day or two. Then I pull up pads and add this Fun stuff. I have to order the Koop Clean from a store that is almost 40 min from me. I know that it is totally worth the wait, time, and money.I did get 8 packs myself, I had to drive 41 miles one way to get them. I am planing to do the switch from sand to Koop clean in my coops this weekend. Also I will have some in my brooder next month when my chicks arrive.
