orloff russian

Help! I bought 4 chicks (2 partidge rocks and 2 Orloffs) back in February, then went back a week later and bought 2 more (an Easter egger and a cuckoo maran). They were all supposed to be females but I’m starting to think my orloff isnt a pellet…. Sally (Sal) is the same size as all the other...

I’m new to the chicken scene and have a few chicks (all of which are different breeds). I do love my little Orloff! This chick is 4 1/2 weeks old. Any guesses on gender?! I haven’t had a whole lot of luck on Google searches about this breed. Thanks for your help.
