1987 M. Stanback 3 M. formicivorus UA2 H N H R (12 April) Egg # Date Laid L W 1 8-9 April 25.7 19.1 2 8-9 April 24.7 19.6 3 10 April 25.4 18.9 4 12 April 25.1 19.8 13 April 1500 still 4 eggs - I'll assume clutch complete 14 April Fucking A. It's now a Fucking experimental Fucking group. 20 April 1400 Gluey thread on egg #4 . 21 April 0900 No sign of pipping yet. 22 April 0700 " 1630 Egg #3 pipping. 23 April 0715 Eggs #1-2 hatched. #2 seems to have hatched First (but who cares) Egg #3 has progressed very little. Egg #4 pipping. I put a drop of blue on in #4. Babies marked RL = 4.8 -1 = 3.8g (bg = 1g) LL = 4.0g The method I used for dying is as follows. With every board, thin the shell at the apex of the pointy end. With rapidograph, poke tiny hole barely thru the shell. Touch I drop dye to this hole and allow capillary action to take dye into egg. 24 April 0800 Well, the dye didn't kill the chick - but it didn't mark it either (capillary action wasn't noticeable yesterday). And neither chick from yesterday was still marked. So today I put on lots of rapidograph ink. I'll assume the biggest babies are from yesterday am, and the smallest from #4.
