Hello all. Just joined the site. Have often come here for much appreciated information from all the expertise of the members here, and decided to join this Spring. I live on a decent-sized place in the country, just outside historical Gettysburg PA. Have had chickens for @ ten years, and kinda' learned as I went. Think I've been pretty fortunate with them. Never had more than ten or so, and unknowingly bought a straight run of them, and ended up with nearly half roosters. The chickens have become pets, so I don't slaughter, and ultimately decided I would wait till the roosters passed on before adding more chickens. Well, that has happened this winter. So, then brings me to a request for advise My last rooster developed some sort of lameness. Would lay on his side, and if I tried to see if he could stand, seems very unbalanced, and would fall forward.... Not sure if he caught something, or ate something, (or that he was ten years old...) or what. And unfortunately on our last cold snaps of the season, he did not make it. So I have an empty coop. Cleaned it out, and have kept the windows open (thinking the cold might help "kill off" anything that might be related to my last guy's ailments... We had a couple nights in the teens....). But am thinking: might there be some sort of ... "bomb" treatment I could do in the coop... set something off in it, or perhaps spray it down with "whatever", to ensure when I introduce new chicken, they won't run the risk of getting anything residual... Might someone have a suggestion? or would it seem keeping empty, and airing out for the last month or so be adequate?. I don't want to spray or treat the coop with something and potentially trade one risk for another... oh, so did stray from the intro, so sorry. Really appreciate all the good info (and stories ) of other chicken owners. P.
