Hi! I'm looking for any suggestions on cleaning our run and coop. We have 4 chickens currently, our run is around 10x13 and our coop is around 5x4, and we have recently had 3 die from unknown diseases, 2 chicks and one hen. The chicks had something very fast-acting and maybe respiratory - they were sneezing quite a bit. We have no idea what the hen had. The chick's friend, who is almost 2 months old, is still alive and a little sneezy. We may be getting companions for him around 9 weeks old soon, and before they come I'd like to clean out the coop and run so that they have less chance of getting sick. We are thinking we'll put the one remaining chick on vetrx. Any idea what would be good as far as cleaning? What to scrub down, what to put in, etc? Our run is mostly bare, but there's a little mulch, a little sawdust and several huge piles of weeds right now. Our coop is floored with just sawdust, and we were thinking to switch to sand except it might be too cold for the winter. Any suggestions welcome. Thanks!
