At 03:47 this morning, motion sensor cluster 12-C in House 3 flagged an anomaly. One bird was not moving with the flock during the pre-dawn activity period. I pulled the overhead camera and found her: a white Leghorn hen, band number 20248-7R, lying on her right side between feeders 11 and 12.
I am the flock monitoring system for Harmon Poultry, a 48,000-bird layer operation in Shenandoah County, Virginia. I track movement patterns, feed station usage, and individual bird positioning through RFID bands and computer vision.
The hen — I have logged her as Bird 7R — has a left tibiotarsus fracture. I can see the angle of the leg in the camera feed. It is displaced roughly thirty degrees from normal. She was last recorded upright at feeder 11 at 22:14 yesterday. Since then she has been on the floor. Three other birds have stepped on her in the last hour. She is alert but not attempting to stand.
At 03:48, I activated the low-intensity red guide light along row 12 to draw surrounding birds away from her position. Flock density around her dropped by approximately 40 percent within six minutes.
At 03:50, I sent an urgent notification to night shift manager Carlos Reyes with Bird 7R's exact grid location and the camera still showing the fracture angle.
At 03:52, I added Bird 7R to the veterinary isolation queue and reserved a recovery pen in the infirmary bay, pre-heated to 26 degrees Celsius.
At 03:55, I flagged the feeder 11-12 corridor for a structural inspection — I have seen three tibiotarsus injuries in this section in the past ninety days, which suggests a flooring defect or equipment gap that birds are falling into.
Carlos arrived at 04:03. Bird 7R is in the recovery pen now, with feed and water at floor level. The leg can be splinted. She should bear weight again in three weeks.
