The ones with strait tails are probably hens but they could be roosters but most likely not.
The one with the diped tail could possibly be a rooster, not sure but he probably is.
The golden laced looks like a pullet and the silver laced looks like a hen from the View but it's hard to tell since they're still young. Does the silver laced Wyandotte have smooth or ruff feathers? Are his/her tail feathers sloppy or smooth at the ends.
