Table 3.

Frequency of aggressive pecks and displacements per hen per 30-minute observation period (± standard error) averaged over the 0800 and 1700 observations periods.

	Space allowance		Cage size
	Low n = 6	High n = 6	Large n = 6	Small n = 6
Aggressive pecks	0.05 ± 0.01	0.04 ± 0.01	0.04 ± 0.01	0.05 ± 0.01
Displacements	0.14 ± 0.01a	0.09 ± 0.01b	0.10 ± 0.01	0.12 ± 0.02

Different superscripts indicate significantly different main effects within a row (P < 0.0005). There were no interactions between space allowance and cage size.
