Only data from cages containing three chicks were analysed (N chicks groups: 15 CL vs 20 CS, 15 LL vs 16 LS, 9 SL vs 13 SS).
However, proportions of 2-chick groups and 3-chick groups did not differ between sets for the same session (χ2 = 0.49 (LTI chicks); χ2 = 2.71 (C chicks); χ2 = 0.001 STI chicks), df = 1, p≥0.10 for the three sessions) or between the three sessions (χ2 = 0.33, df = 2, p>0.80).
For tests performed on chicks' brood (hand-on-home-cage-door test and human-observer test), frequencies of each behavioural item were weighted by the number of chicks presented (frequency per individual) and used to compare data within a given session (N chicks groups: 21 CL vs 22 CS, 20 LL vs 19 LS, 11 SL vs 16 SS).
For the chicks, groups AC and BD chose corners A and D significantly more than expected by chance (group AC: M = 0.45, s.e. = 0.024; t8 = 5.367, p = 0.0005 and group BD: M = 45, s.e.e
Each chick in group 1 was intranasally inoculated with 0.1 mL of 105.5 median embryo infectious doses of strain ck/CH/LDL/091022 [ 14] at 15 days of age.
Simon Renshaw, a Firm executive who manages the Dixie Chicks, a group embroiled in a contract dispute with the Sony Music Group, put it this way: "I don't think we are litigious.
At the 49th annual Grammy Awards in February, the Dixie Chicks—a group that had received little country radio airplay in the extended wake of lead singer Natalie Maines's critical comments in 2003 about Pres.
Chicks in group 2 served as virus-free controls.
Chicks of group B exhibited abnormal signs and behaviors throughout the course of study.
The results revealed that chicks of group A showed normal signs and behaviors.
Chicks of group B showed less attraction toward feed, while water intake was increased.
