Do Rust patches on Easter Eggers guarantee the chicken to be a cockerel?

[RLynn]

I have a mixed flock of 5. So far two of my 5 ‘pullets’ are showing undeniable signs of being cockerels. Large red combs/waddles and size for 4.5-5 weeks old. Now I am completely paranoid about my other birds ending up being roos. I can’t have roosters unfortunately. My EE’s feathers are starting to come in and I am noticing rust color patches coming through. Is that a guaranteed cockerel? I have some photos of (hopefully) her, although I know she is still too young to be sure. She is about 4.5 weeks. Just my luck all my ‘pullets’will end up being cockerels! Anyone have hen EE with rust patches?

Still a little young though to be sure
