Sorry I can't help you since we are so close but all my hens are 1 year plus. I do have a bunch of chicks hatched middle of Aug. If you can't find anything else. Hope you find what you are looking for.
My sister has a FREE mostly australorp roo around 1 year old. I say mostly cuz the guy that hatched him said that is what he is but he is not solid black like a true australorp roo is saposed to be.
ANYWAY HE IS FREE!!
That is so cool that you are giving them away FREE! I just wish I lived closer so I could get some.
Who cares what breed they are lol a free chicken is a free chicken!
