Speckled Sussex Pair Boy/Girl?

[JMBern]

I have two Speckled Sussex chicks they I picked them up on the same day.
given that they may be a day or two different in age its definitely not a week or so different.
the first three images are of Houdini Or Houdina though I'm believing more and more that it's a cockerel.

there is even some great iridescent greens that show up on the back (not in pics though)
The second set of images is his counter part Yella Bella she is the smaller and very different. can anyone confirm my thoughts on this?

Looks like a cockerel/ pullet pair.
With Houdini being the cockerel and Yella Bella being the pullet.

thank you for confirming my suspicions.. being our first flock I was skeptical
