I started with mature birds in march. All was going great until summer started. Then I got 1 bird with a prolaps, 1 bird egg bound. one bird with a neck injury, one bird with and injured toe, one bird with heat stroke and the other survived an encounter with a dog, then had her led broken by my rooster. Seems like I have had at least one house chicken every week. I just lost my chicken with the broken leg. Despite my best efforts to keep her comfortable dh thinks the stress may have been too much for her. A few days ago I lost a chicken to a broken neck from an unknown source, and today I lost one to a lightning strike in this bad storm. so far I counted 4 in the coop plus the rooster, so one is missing, may be hiding out somewhere else in the storm. But might be dead too. Arg!
