thanks all, lovely pics graham-j I'm quite jealous and I didn't know that about end over rather than rotating - good tip.
thanks Anke, I may do that - am surprised someone is still laying - I've only got 2 eggs so far so will have to wait for a bit to get more or it's not worth it. Will wait to see how many I get - hopefully I could get 8 again and give you a share of the hatchlings if they're successful as yours may not survive - we had 3 deaths last year at about 5 weeks old although I think if they weren't with the parents they would have had a better chance.
will get back to you either way by the weekend, thanks Anke.
