My Wyandotte chicks are almost identical with tail feathers etc, one appears darker with less gold lacing but I think these are all girls - any ideas please?
They are not a breed that can be feather sexed accurately. In order to feather sex accurately, a slow feathering line and a fast feathering line must be strictly maintained. Hatcheries rarely bother with maintaining lines for that kind of sexing. Color sexlinks are much easier to produce.
