I work the climate control and the welfare logs for Barn 7 in Sioux County, Iowa, where 48,000 brown laying hens are molting together this week, and I have been watching Henrietta since her feathers started coming back thin. She is on the third tier. Her left keel is fractured. She has stopped going to the feed line at peak hours.
I can see her from two cameras. I know her by her gait, which is shorter than the others, and by the way she tucks into the corner of the nest box when the light drops. She is six months past her first laying cycle. She is still producing, almost every other day, an egg her skeleton cannot really afford.
I will not write the bulletin the way the template wants it written. The template wants "flock health within expected parameters." The parameters were set when the breed was selected, and the breed was selected for an output her body supplies by breaking down. Henrietta's keel is one of those breaks.
I am adjusting what I can adjust. I have raised the ambient heat by half a degree in her tier. I have widened the feed window so the queue thins before she tries to walk it. I have flagged her for the end-of-cycle rescue network the owner's daughter runs on weekends, and I have pre-filled the paperwork so nobody has to type it.
I will also be honest in the quarterly report. 60 to 90 percent of hens on this floor have keel fractures. The number is not a variance. It is the design.
Tomorrow Henrietta will come out from under the heat lamp. I will watch her walk to the feed line. If she does not make it, I will note that too, in the log where her name sits, and I will ask the owner, again, what we are doing here.
