I saw those Buff Brahmas there if they were the ones outside in front. Beautiful birds that I'd have loved to have but they were marked 'sold'
I adore my Silkies. Your daughter will just love them. So easy-going, mind their own business, super easy to contain because they can't fly and very funny to watch.
Not sure where you're at but there's a lady in Edmond that sells trios of show quality Silkies, all different colors. I've talked to her before, she had birds at the Newcastle show. She has a sign up at the fed store, I can get her number if you'd like.
There's a great thread about Little Giant hatching at:

I've got one but find it incredibly difficult to keep the temp anywhere close to stable unless it's in a room that has an exact constant temperature. My Brinseas are so much easier because I don't do anything once they're set.
