This is the picture of the eggs showing a small hole (in far egg). It might be rather difficult to see at this scale (and it might be just a trick of the light, or my fertile imagination). This was yesterday afternoon, which made me assume hatching would happen last night, but I was wrong. Serious incubation started on 28th August, so hatching should be 26 Sept – 1 October.
As Deborah pointed out last night, Diamond is showing signs of impatience for her chicks to hatch. treating the eggs like skittles. Last night the average time spent turning, stretching and egg rolling was 6.5 minutes (it’s usually about 1.5). So pretty restless, although it was quite a warm night last night (and some light rain). Here she is apparently trying to initiate some action.
