Breed and gender help please

Blue egg laying breed roosters x Cuckoo marans hen would create sex-linked olive eggers where the cockerels would look like this.

Olive Eggers are mixes and can be any color! I have a couple that look like welsummers and my cockerel is black and white.

Also, I'm still pretty confident yours is a male. You can always wait until you hear a crow but have a plan ready if you need to get rid of him.

I will have a plan. Thanks.
