She actually has quite small white eggs. It's her first season laying, she's only about 7 months old,is it usual for small eggs at first?

Well, that kills any thought that your hen might be a Black Australorp as they are brown egg layers. You will have to post a picture if you want her breed identified. In answer to your second question though, pullets do lay smaller eggs when they first start laying and the eggs get larger as they continue laying.
