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.
