I'm sure at this early of an age, all are probably too young to properly sex, but guesses are welcome. Group photo in the coop. 1 Gallon Drinker and 7LB Feeder for sizing. Silkie 1 - 3 Photos Silkie 2 - 3 Photos Silkie 3 - 3 Photos Silkie 4 - 3 Photos Silkie 5 - 3 Photos Silkie on far right Silkie 6 - 3 Photos Silkie 7 - 3 Photos Silkie 8 - 4 Photos This one couldn't make up its mind on whether to have 4 toes or 5. Silkie in the Background These puffballs are all 8 weeks old. After digging around the internet trying to find out the best way for sexing these guys/gals, most photos that I have seen of Silkies in the same age range didn't appear to be as developed or as large as our babies. I have seen all silkies exhibit cockerel behavior such as Hackle flaring and chest bumping as another post on this forum suggested was an indicator of possible sex. I'm not sure that behavioral traits would be 100% accurate, but even though all sometimes exhibit the aforementioned traits, only 3 make a day long project out of it. Those three also "spar" with the 2 Bantams which are Roos. The only crowing from the coop are the two Bantams, which are the same age to the week as the Silkies. Another thing that I've noticed is that their feet range in sizes from tiny to full grown Yeti... what's that about? Bantams: Silver Sebright? Booted? Long feathers on feet and legs. Lastly, another group photo. Edit: Silkies are numbered for ID purposes... Our 2 year old daughter named them all... "Muffin". She apparently is just trying to keep things simple.
