Has anyone ever had any luck trying to feather sex silkies? I've got 5 5-day-olds and I noticed that 4 of them have significant wing feathering coming in while one does not. Also, for the fun of it I tried the whole flipping them over on the back thing and the females lay there and the males squirm.. the 4 with feathering all were calm and the other squirmed... I know they are suppose to be impossible to sex until they crow or lay, but just curious if anyone else has experimented with this and has had any luck?
