I was on here last week, had a dying brown leghorn. Thanks to a nice forum member, I kind of came to the conclusion, that it was probably just low bird, who was weak, she had weight loss, and was acting meek. Now 1 week later I had another one die, seems different. I didn't notice anything unusual, just that she was in the next box when I put em to bed ( which was rather early, we have been having below zero weather and its hard on man and beast alike) The coop is 20 x 30 cabin, I have 23 chickens in there, it doesn't get below 30, they eat layer feed, and scratch, I get from 12 - 18 eggs a day from 22 hens. Everyone else seems "healthy" but so did little Ollie, (the turken who just died). I found her in the nest this morning, her eyes closed, and when I picked her up to bring her in the "hospital" (my bathroom) I did notice she was breathing heavy, and kind of a wheezy sound, she let out a big puddle of black and yellow liquid, and I set her down. She was gone in less than an hour. Is there anything I can vaccinate with, or precautions to take? Is this part of winter in a chicken coop? Does this sound like a disease, the first one came in for a day, ate enthusiastically, and the next day died. This one was healthy, and just went.
