Oh, I am so very sorry but you did what you had thought would be best and if you were not going to be there to watch her like normal it was best to keep her in the run so nothing would get at her so please don't blame yourself. We all do things that are for the best and unforseen things happen. You did what you thought was best for her. It does sound like the heat was what had gotten her. It is so hard to lose one like that.
I recently lost my blind girl in the rains and flooding. Instead of putting her in her run because she would get wet in the rain, I kept her in the coop and she managed to get out of the coop and get lost in the pasture. I searched for days in the torrential rains and I could not find her. After everything stopped, I took my dog out with me to look again and he found her but I was too late. She was dead. There was so much water and it was also cold and she couldn't hang on. I felt terrible that I did not put her in the small coop & run that day but I thought she would be warmer and drier in the big coop. The sad part was she was only about 75 feet from the house and the grasses were so high, I could not see her there and I searched all over everyday and never seen her until the rains stopped and the grasses were by that time laying over from all the rain and my dog took me there.
If your girl was broody alot, they do pull their breast feathers out so they can get better contact with the eggs and keep them warmer. So, maybe that was not a sign of another illness. It does sound like the heat was a bit too much for her. I am so sorry and I do hope all goes well with your broody hen and she behaves and stays on her nest. I have noticed with mine, they tend to go to different nests when they start out being broody but later on, they get the hang of it and do not go elsewhere.
You have to keep us posted how things are going and of course pics of the new little ones when they hatch!!!
Lisa,
I'm so sorry about your sweet chicken. Interesting that we have such similar experiences. I cried when I read your story. It is so much like mine, so heartbreaking-- we both tried so hard and loved our girls. Your dog sounds like a very good helper to have around. I am so mad because there were only two hot days left in the entire summer-- the day my hen died at 98 F and the following day, also 98 F, and then it cooled way down. Had my trip been 3 days later, I'm sure she'd still be alive. Just maddening. I'm going to post a photo of my hen's picked out breast feathers. She was broody back in May, but we broke her of it in early June, so she hadn't been broody for about 9 weeks or so. Should her feathers have grown back in by the time she died if she had been feathering her nest while broody? She had been laying eggs again and her legs had turned white.
