Experiment 1: effect of stunning method (mean ± SE (range)) on time to return of rhythmic breathing, neck tension, and balance in broilers and laying hens.

Stunning method	Bird type	Mean ± SE (range) time to return of rhythmic breathing (s)	Mean ± SE (range) time to return of neck tension (s)	Mean ± SE (range) time to return of balance (s)
Head-only	Broilers (n = 24)	33 ± 2 (17–59)a	113 ± 14 (39–306)	182 ± 22 (66–512)a
Head-only	End of lay hens (n = 23)	24 ± 1 (19–39)b	76 ± 4 (45–138)	111 ± 6 (75–176)b
Back-of-the-head	End of lay hens (n = 25)	34 ± 2 (20–53)a	76 ± 4 (52–115)	260 ± 36 (80–974)a
