They look similar to my Welsummers. Cream Legbars have a more gray-ish color to them, along with a variety of patterns stretched across their wings and back, and a slight crest. Welbar chicks also look similar to your chicks, although they have a brown cape (or large stripe) on their back, which your chicks do not have.
How old are your chicks? I think we can better tell the breed if you could update us with pictures of them at about three weeks and up!
