I have a few Golden Comets, and I love them! My girls are super layers, very docile, and very pretty

Personally, I love my barnyard mixes better than pure breeds. So far

fl ) I haven't had any illness issues with any of my mutts. They are hardy, good layers, pretty, and sweet. It took them a while to get used to me, but now they come with I call, and they get all underfoot whenever I'm outside.
Nothing wrong with hatcheries, I have some hatchery chicks myself, but definitely buy local if you can. It helps support your local backyard chicken keepers, plus you can see the birds before you buy, which is always nice!
I second the giggle about getting over your head.

Before you know it, you'll be wishing you had more, and more, and MORE!
