(8 Jun) 1600 Climbed hole - 4 Fresh eggs! But cutting is a chore.
6" thick live sycamore. I make less than 2 of the
cuts and that takes @ 1 hr. I blow out as much
sawdust as I can before coming down (but 2 of the
eegs are still covered) Sorry, but I'd be up there 2 hrs.
9 Jun 1530 They didn't seem to mind - they laid 2 more eggs.
I Finished the cut and marked all 6 eggs (2 seemed
Fresher so I marked them as such. There was a runt
egg (the 6th). I removed it - things are getting tight in
there and I want no wasted space. (When was it laid)
14 Jun 0930 Oh shit. I cavalled the runt egg and saw no yolk, so
I blew out the contents - and found a yolk (this was on
13 Jun) On 14 Jun I climb hole and see they didn't
lay more eggs. Since they had 9 the First nest
I Figured they'd lay 8 in this. So, Final clutch = 6.
However, I removed small egg : 5, and now I see that
they removed an egg, so clutch is now 4.
