Ok, so here in Montana we are having a pretty tough winter... colder than usual. No big deal, I have 5 Buff Orpingtons and 2 Araucanas. Both are cold hardy, sweet birds. When we got our second cold snap, it was -7 degrees at my house for the high for one full day and 2 nights. During this, one of my girls was kicked out of the coop for reasons I do not know, and the day in that temperature proved too cold for her. She was gone when I arrived home a short 3 hours after my husband had last checked on her, brought her in the house and tried to get her back in the coop. I had intended on bringing her in the house for the night, but those plans clearly were cut short. I posted on here then... wondering what she could have died from assuming no way was it from the cold. She had posted up in a sheltered space, on clean straw. In any case, we summed it up to being she was sick with god knows what and shunned from the coop, then either succumbed to her illness and/or the cold. When I did a check on her body, I did notice swollen feet. Not bumble foot, not mites... but swollen feet. I thought frostbite (maybe early stages before black and shrinking)... Now, I have another hen with one deformed and swollen foot! I took her in the house, both feet warm to touch. We gave her a nice bath, soaked her feet in betadine solution for about 10 minutes, put antifungal and mushers secret on both feet and wrapped her bad one. It is deformed due to the swelling, and she refuses to put weight on it so I know it must hurt. She is all comfy now and sleeping in the house tonight, and likely for the next few days... The swelling reminds me a lot of my other girl that didn't make it! I know its hard without pictures but my phone had died and I wanted to get her feeling better, so chose to care for her rather than worry about photographing the whole incident. Her foot doesn't seem to cause pain with I move the toes back straight (they have curled up together) so I made a little boot out of cardboard and wrapped them to it. Please, anyone... what in the world could this be? After loosing my other girl, I have stopped letting my chickens have so much access to outside in the snow during these cold snaps... but its not even that cold anymore... it was in the 20s today (10 this morning). They get let out for 20 minute periods about 4 times a day. I don't want to lose another... tomorrow I think I will do another round of cleaning, so I will try to snap a few pictures then... why do feet swell outside of bumble foot?
