How old are these bantam buff brahmas

[tallyho]

I got these two cuties at one of our boutique feed stores. They are from a breeder who sells her extras to them. They were the last two in the BBB bin and you know what that usually means...boys! I just couldn't stop myself and I had to take them home. Can anyone tell me how old they might be and could it possibly be that the last two were actually little girls? They look exactly alike. It's hard to tell them apart. No pink on the combs or wattles yet. I've never had any kind of brahma so I don't know how the combs develope. My bantam cochin boys were obvious at 3 or 4 weeks. I have had these two for about 3 weeks.
