Figure 1. Synchronisation of behaviours (A) and proximity (B) in sibling groups during the hand-on-home-cage-door test.

Figure 1

(A) Frequencies of observations (mean ± SEM) when all sibling chicks performed the same behaviour during the test, for each mother group. (B) Frequencies of observations (mean ± SEM) when sibling chicks are close together during the test. LL: LTI chicks reared by LTI females; LS: LTI chicks reared by STI quail. CL: control chicks reared by LTI female; CS: control young reared by STI quail. SL: STI chicks reared by LTI females; SS: STI chicks reared by STI quail. Post-hoc Bonferroni test: ** p<0.01; ***p<0.0001.
