Picture 1) The first chicken- smack in the middle of the first picture- that looks cockerel to me- not knowing any ages - since that one seems to have more going on than anyone else in the shot- OR- they are a pullet- closer to the POL (slow shrugs) Perhaps this chicken has a bearded booted bantam mix in there..?
There looks to be a silkie pullet in the front, left hand side of this photo.
The black chicken looks pullet from what I can see- not the face- can't see any 'cockerel' feather tells - not here at least . Not a Cochin. Not a dutch. Wrong shape for a OE, Japanese, or serema. (Slow shrugs) Not a booted or silkie variety...
The others are in motion... but the coloring and shape makes me think they are kin to the center feature chicken.
Picture 2) This looks like a pullet. Maybe an EO mixed with a golden sea bright?
Next two pictures - are these silkie/ silver sea bright mixes..?
If so, I'd GUESS the one with the fuller fluff would be a pullet- but... (shrugs) I have no experience with sea brights or breeding silkies or what would be dominant or even if the same tells would be tells
Just looks like that's what it could be, you know? Lol
Hmm... Well, If we go by they are all the same age- but they are a silkie/sea bright/ booted bantam mix- Not knowing the age- but comparing em to the first guy- I'd say... it's too soon- - but I'd lean pullet on them - but I sure wouldn't place bets!
