Hi! I went away to Ontario for 10 days on the 21st, and before I left, It was a couple degrees above freezing, and the chickens didnt smell, at all - even people who rarely came to my house said that. Now, the RUN is what stinks, the coop needs to be cleaned desperatly, because the girl who was watching my chickens, didn't collects eggs once ( I found 38 intact eggs, and many many shells.. ) and didn't spread any new shavings in the coop which means the poop just built up.. but even like that - the coop doesn't smell nearly as bad as the run! THe run is 450sq ft, UNCOVERED.. and it REEEEEEKS! The ground is frozen, which I think might be part of the problem.. but when i'm home, i let the chickens free range the 2 acres, and they didnt do that in the 10 days I was gone... I don't know what to do now.. I've covered the coop with a fresh layer of shavings ( i cleaned it fully a week before i left) How do I make the run smell better?
