Ok I got these three chicks from some city guy who got the eggs to incubate for his kids to watch hatch out. He couldn't remember the breed or anything about it but said they might be all roos which makes me think black sexlink. I think I have it narrowed down to plymouth rock or black sex link. Need help I am hoping for at least one hen as I already have 3 roos that are gonna have to be narrowed down to one or 2. They have some black coloring on the top of their feet going up the front of there legs. They all had white spots on their heads but don't seem to have any of the reddish feathers like the sex link is supposed to have. Got the best pics I could it is there first day out in the enclosure. Picture taken today and I would have to say they are around 7 weeks old. Chick #1 lightest of the 3 which I want to say is definitely going to be a roo Chick #1 face/comb Chick #1 feet Chick #2 Darker than #1 and I have no clue Chick #2 face Chick #2 feet Chick #3 was almost black and is just now getting more white. chick #3 face Chick #3 feet Photo of the 3 of them together.
