I'm still fairly new to this whole backyard chicken raising. I have a small flock of 6 Buff Orpingtons that I have had for the past 2 years. Everything has been great up to this point. The past few days I noticed that the comb of one of my ladies was pale (almost whited over) and a bit droopy, her feathers were a bit out of sorts (but all my chickens have been molting lately) and she was mostly keeping to herself and not pecking around very much. I attributed this to her molting, (as I was told could be the case from some of my neighbors that keep hens.) Lately my flock as a whole has been laying less, I might get 1-3 eggs a day now. But I live in NJ and thought it was just from our change of seasons and the fact that they were molting. Anyway, this morning I found her lying against the waterer outside of the coop in their pen, wet (it rained last night so I'm thinking she may have been there all night.) She didn't get up and come to greet me and look for food like they all do every morning that I go out to tend to them. I removed her from the pen and put her in a carrier on my covered porch with food and water, but she is dying and will pass soon. I'm concerned about the rest of my hens, (and myself honestly.) Any ideas on what it could be and how I can prevent it in my other hens or what other precautions I should take. Thank you!
