720. Checked hole: 7 eggs!!. Egg was long (suggesting
♀1533?). (But ♀1533 laid late yesterday (>800) suggesting she was done.)
730. Watching.
758. ♀1533. ♂1613 looking, but left. ♀1533 enters.
839. ♂1613 at hole, leaves.
844. ♂1613 at hole. ♀ looks out, leaves. ♂ enters.
845. Checked hole: still 7 eggs.
Well, I think ♀1531 laid today, given that ♀1533 seems
to have laid her last egg yesterday and is now acting very
broody. (Given that ♀1531 laid earlyish, she could lay
again tomorrow, so I should be ready to look once again!
7 May
Monré watched and reported that none laid today, although
♀1531 acted as if she was thinking about it. In any case,
this would appear to be all here.
11 May
1015. Still The 7 eggs. Egg #6 ♂ is dented a bit at the air-hole
end, but all eggs appear to be developing.
15 May
1845. No hatching yet.
16 May
745. Eggs 1-5 hatched. Eggs 6&7 look fertile and close. All
I did was mark the 5 babies with some enamel so I will
(hopefully) be able to distinguish them later on today from the
late-hatching babies.
1620. Checked nest again: all but egg #6 hatched. See back for weights.
18 May
1400. Checked the nest: all 7 babies OK, although I probably on the
way out (the newly hatched baby from egg #6). Remark ed. Also
put in a parasite board.
19 May
1945. Watched broosting. ♂1613 came, followed a couple
minutes later ♀ 1614. After this 2nd bird entered
