Woke up this morning to let the chickens out and everyone woke up & was acting normal as always and then I went back to bed for about 3 hours to notice my 2 year old ee hen [a month from 3] laying dead in the run. Overall she was healthy, wasn't over weight, never had any worms or anything, no outside injuries and was laying on the ground with her eyes closed dead, she had even laid an egg just 2 days ago, as she laid about every 2 to 3 days on average. I'm so upset and cant imagine what would have happened. She showed absolutely no signs of anything. Flew out of the coop this morning, ran/walked around just fine, pecking and looking for grain and then within 3 hours just laying on the ground dead.
