We lost our first hen today from our flock of 7. It was a little bit sadder than I anticipated. She is an "easter egger" about 8-9 months old. Was the only one that hadn't started laying yet. Last night I kicked her out of the nesting box once (she was the first one in the coop before bedtime) and then I think she ended up sleeping in there because she couldn't get up on the roosting bar. Came out this morning and just sat down, breathing very heavily. I had to go to work - my wife said the breathing got worse and worse, and finally the other hens starting squaking in alert. Wife picked her up and held her for a bit, put her in a laundry basket and isolated her from rest of hens. There was clear fluid coming out of her nose and cheeks turned very white. She took a violent last gasp and that was the end. Less than 12 hours from first noticing any symptoms. I don't really know anything about chickens or possible diseases - any ideas? I'm obviously worried about my other six ladies, who all seem to be acting fine so far. Energetic and happy. I've also read a ton in the local media about lead poisoning in chickens from backyard soil contamination (I live in Berkeley, CA). I'm probably a little over-paranoid about that, but I can't help but think about it.... I'm open to any thoughts or suggestions. Thanks!
