Re-transformed late nestling growth (a), fledgling body mass (b) and tarsus length (c) in relation to maternal immunization (control vs. LPS-immunized females) and brood size manipulation (control vs. enlarged broods). Least square mean ± SE derived from final models are shown. Open circles denote control broods, whereas filled circles denote enlarged broods. Sample sizes are noted above bars. Significant pair-wise differences are marked by * (P < 0.05), ** (P < 0.01) or *** (P < 0.001)
