I opened 9 hives here in Canberra on the 11th of August- the first warm day of late winter- 17c. 2 of the weakest hives showed somin strange.
I had a look on a few forums and it seems that sometimes queens coming out of winter seem to take a little time getting back into the swing of laying individual eggs in individual cells. From Michael Bush talking about myths:
"Queens will never lay double eggs.
(In other words, all multiple eggs are a sign of a laying worker).
I've often seen double eggs from a queen. Rarely I've seen triples. I've never seen more. Laying workers will lay from two to dozens in one cell. I look for more than two and eggs on the sides of the cells and not in the bottom. Also eggs on pollen. These I consider signs of laying workers."
It looks like 6 or 7 in some cells. The queen was present in both of these hives and the eggs are in the centre of the cells. My guess is that this time of year the queen has an imperative to lay but the small cluster size has reduced the area warm enough for her to lay in so she just keeps laying and the workers will eat the extras.
Hopefully I'll be able to check again in a week or 2 and see if she's settled down.
