No one has patience for pictures like a silkie. I think their annoyed faces when I keep touching them to move just right or look at me are the best. They have to raise their head and tilt it to give me the evil eye.
Partridge is sexable by color pretty young. Ive known those 2 were girls since 6 weeks. Most girls are easier to sex. The combs on the boys are starting to come in. Girls in my birds have very small or no comb. Tiny wattle bumps on the boys are starting to become visible. Girls don't get any wattle and they are small on boys. The boys are also noticeably bigger mostly. Pick them up and they have heft to them. The girls are fluff.
The 2 I'm not sure on are probably boys. I do get a few boys that are hard to be positive. They are only slightly bigger than the known girls.
I had one, one year, that weight, comb, and wattle identified as boy. His feathers were very girly until around 16 weeks. Then he started getting the head streamers and adult feathers.
The issue with the orange gene that pops up in partridge silkies is what usually causes the hard to sex boys.
