Table 3. Exact binomial tests of probabilities for higher protein food consumed first (0.5) and for whether consumed within the first two foods consumed by chicks (0.83) across the test trials.

Test day	Frequency of higher protein food consumed first	P-value for first consumed food	Number of chicks that participated (consumed food)	Frequency of higher protein food consumed within the first & second choices	P-value for first & second food consumed
Day 5	20	<0.001	25	25	0.015
Day 10	17	0.169	26	26	0.015
Day 15	13	0.839	24	23	0.107
Day 35	10	0.092	13	12	0.710
