TBH I 1000% agree with you, but I think Iva Jean is intersex. LOL.
I ended up getting her a cheap DNA test, and it came back as hen...

so I did a 2nd one, and it came back as hen again... Though, SO much about her reads "rooster". The comb is big and really red compared to ALL the other girls, she stands like a rooster, she's even getting a rooster tail... let alone the coloring. so the results still don't have me convinced "she" is 100% pullet...
Though, the vet basically explained to me, though it's rare, some chickens are intersex, and some just defy genetic norms. But her best guess, because the DNA test I chose just tests for the "W" gene is present or not, that it can easily be a "ZZW" or have half ZZ/ZW (and a ZW was the spot tested)... She said we can do some more extensive testing if I want to pay for it, but I think I'm just going to wait to see what happens, and just do a nacrospy at the end of her life for comfirmation some other time.
For now, Rose/Iva seem to get along fine. It seems like me moving them around a few times a day keeps them more in "alert" mode than being aware of each other. Rose is def in charge though, between the two. So far none of them are attempting to mate yet, so that might end up chaning when that happens.
When/if it ends up being an issue later, I plan on culling Iva though. Just because I did want a rooster for fertalized eggs, I don't want to risk the chance that, even if Iva doesn't lay eggs AND mounts other chickens, she might just shoot blanks or have a lower fertility rate, just because of the "W" is def somewhere in there. Figured I will just have better fertalization odds with the very obvious rooster.
If they don't end up having any issues though, we figure we might as well keep her (even if she doesn't lay eggs)

cause I don't really want to cull anyone if I can avoid it. And I'm just curious at this point what will happen... LOL
