Hi members, I found the exact age when male peachick had shedded innermost juvenile primaries 1st, was 27 days old. At 27th day the peachicks have 8 juvenile primaries, because innermost juvenile primary flight feathers had been shedded, and outermost juvenile primary flight feathers 10th are in pins. I found the likely measurement for 3 innermost juvenile primary flight feathers, but not exactly. P. 1st 134 mm P. 2nd 148 mm P. 3rd 162 mm If these measurements are not correct, you can send me the correct measurement, but the feathers must be hold FLATTEN on table / desk to measure. If day 27th (age) is not correct, please tell me the correct age in days when both male and female peachicks shedding their 130 mm-134 mm innermost primary flight feathers 1st. I appreciate your help. Clinton.
