A few 'blogs' ago (in the Retirement category), there is a picture of Ellie, our Umbrella cockatoo with our younger son's girlfriend. I should, perhaps, have mentioned that, a little before Christmas, she laid an egg (the parrot, not the girlfriend) - followed, shortly, by a second one..
Last month, she laid another two and, yesterday, a fifth one!
There is no doubt these eggs are unfertilised. However, the fact that she has chosen to 'burrow' under the duvet on my bed in order to lay them between my legs has caused much amusement to several of those I had thought would be rather less frivolous and show more respect to someone of my vintage..
