is this guy a rooster?

 I picked him (I think) on the 7th, figuring would most likely be a cockerel.

 I figure was about 4 weeks old.

 Was noisy almost all the way home.

 He has a bigger comb started that the much older pullets I have outside now, is that a sign?.

 I also wonder what breed he may be.....

 I should have added, I am new to raising chicks, have only dealt with older birds before this spring.

 I lost 3 chicks from first batch to snakes, and one escaped when the first snake ate two.

 Only have 2 of the first 6 left now, and I should put down some more snake repellent.

 Rat/Gopher snakes they were. 

 the two left are doing well, one golden, one red.

 I have 3 newer pullets in with my maybe rooster, two are feather feet.

well, will see when he gets bigger and grows permanent feathers.

 I have a barred rock hen, and two reds, but I think only one or two are laying the few eggs I get. One egg every other day, except one day was two eggs.

 I should post some pix of the two bigger pullets, as they are about what colors they will be. One red, one kinda gold. Not sure how big they'll need to be before I can safely put them in the big pen.

 Around the size of large pigeons or so now, but a ways to grow.

 Well, he cost only $1.19, where the pullets cost $2.49 each.

 He was from the batch they called "Mill Run".

 My neighbor bought a batch of those a few years ago, and all turned out to be Roo's, LOL. So odds are that he is a roo too.

 I have no idea as to how they sex em when they are teeny.

 I grew up mainly in cities, with some summers in the country back in the 40's.

 And yes, I did know where eggs and milk really came from. LOL :P
