How old are they? And about the comb...

[Othercat]

On May 30 I bought some chicks and I was so excited about getting them that I forgot to ask their breed, gender and age. Is there any way to figure out how old they are? Here's a picture of them the day we got them. Anyone want to guesstimate?

We suspect they are two different ages because 4 of them are about 50% larger than the other 3.

Also, does comb growth indicate sex? Because some of them (even the small ones) have bigger combs than the others.

I would "guesstimate" they are about 5 days old in that picture. As far as the different sizes, could some of them be bantams? If the feather development is roughly the same in all of them, it is possible they are the same age but some are large fowl and some bantams. Comb growth CAN be an indication of gender but the biggest indicator is the comb color. If the comb starts to turn pink at an early age, you most likely have a boy.

Are the front ones meaties(Cornish x)? If so, that would explain the size. They look about a week old.

The tail feathers typically start coming in on my large fowl in the 2nd week, so I would guestimate 2 weeks. The white ones could be white rocks.

Actually, with the exception of Earbud (yellow, right) these are all the small chicks.
