Hatchery orpingtons

[PJinx]

Hello everyone I'm making this post because about a month ago I bought some baby chicks from Meyer Hatchery. they were all supposed to be sexed pullets, but I'm starting to think that more than half of them are actually roosters... I've attached some photos of 2 of the 3 in question(the one not pictured is my blue orpington with one leg and that one was hideing from me) the ones in question don't have tail feathers yet but there are two in the group of five that I bought the do have tail feathers. The ones with tail feathers I'm pretty sure are female as that's how it was with my first batch of orbington that I got from Tractor Supply they started to get their tails before the male did. Any guesses or anything on if these are actually female would be really helpful I understand that these are probably also too young to know for sure but any guesses would be very much appreciated.

Sex by comb and wattles, not feathers.
How old are they?

Tail length and rate of feathering are random so that doesn't mean much.
However
The birds do have large combs for their age so imma say cockerel for both of them for that reason
