Responded to a craigslist advert for 25 laying hens, free. The owner claims they are 18 months old but I don't know if that's true. When we were given the birds there were 28 in all, 2 roosters (?), and a funny looking one. The owner said they were given to him and he had no idea of the breed, only that he was getting about 12 eggs per day. I've been getting 17-22 and based upon their appetites when I got them I don't think he was feeding them properly. I gave them some treats to inspire stillness for pictures (yeah, right). I'd greatly appreciate anything anyone can tell me regarding breed and gender.
I kinda thought this one was male, until I caught Oscar sitting on a nest today.

We have a handful of these red (brown?) ones. They are bigger than the others.



The majority of the flock are these speckled ones.


There are two that look like this and we assumed they were the roosters, but I'd expect them to look a little more mature at 18 mos. Was told he looks like a Leg'rn (presumably Leghorn, spoken by an old-timer).

Bonus question: What kind of chicken is this?

Most of the flock from afar.

I can attempt some more detailed pictures if there is something I missed.
