I have a single wheaten marans chick, when it first hatched I thought it was a male because it had a relatively well developed comb. I also looked at it's vent and saw what seemed like a male bump, but I am very new to chickens and don't have any confidence in what I saw, I know vent sexing is far from simple. Now as the chick is developing (now 3 weeks) it seems to be feathering in the shoulders which I have read is a pullet sign. If I had other WMs to compare it to, I expect it would be easier, any opinions would be very welcome. The chick is very against being handled and is a bit of a loner, dominant in a crowd but rarely in a crowd.
I have pictures of all my chicks but very few of this one as it does not like me taking photos and runs if i try. If any specific photos would help, let me know.
