Newbie here. We bought 17 chicks (4 silkies and 13 assorted breed) about 2 months ago. As there are no way to sex silkies, I am expecting some of the silkies might be roos. However, we bought the remaining 13 chicks with the understanding that they are pullets - for some reasons, I strongly suspect that they are roos. Could the sexing experts in the forum give some opinions based on the pic below? Pics are the same chick just different angle - she/ he is 8 weeks old. Many thanks in advance!
