Discussion
- Energy conductance appears to jump up at birth by a factor 3
- Temperature acceleration is assumed
- CO2 production is given weight zero - it was not possible to get such high growth in combination with low embryonic respiration
- mod_1: same energy conductance pre- and -post birth; varying food availability
- mod_2: Pseudo-data point k is used, rather than k_J; Data set tp and parameter t_R are added, the latter replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
