The hatchery cannot send another chick unless I buy two others, but that's fine. I'm content to just work with my two for now.
Now that they're 12 days old their personalities are becoming way more apparent and defined!
Jack is very bold but not aggressive, he wants to be top-chick, but not overwhelmingly so. Max is very inquisitive and determined, but more timid around new things than Jack is. Their personalities really compliment one another, they're going to make a remarkable pair.
I took them outside and let them interact with our older chicks under my watchful eye. At first they both just stayed in my lap and observed, but eventually settled down enough to start investigating. Jack, of course, wanted to challenge each of the strange chicks. Our silkies, who are five weeks old now, pretty much ignored the tiny chick trying to pounce on them. The bitty-bantams, four weeks old now, are comparable in size to my standard sumatras, but much more developed. So though Jack had every ounce of fierceness in him to take them on, they had no trouble putting him in his place, minus one chick who is recovering from injuries and already knows the sumatras. Each time Jack came running back to me and would hop in my lap for a bit. Max mostly stayed close to Jack and I. I had issues with one of the silkies (who is being a problem with all of the other birds), but eventually I got after the monstrous fluff ball enough that she just ignored my little ones. The one time Max did get feisty was when on of the silkies took her spot on my lap. She managed to wedge herself under the silkie and then shove the poor bird off of me lol
They seemed to have fun though! Pecking at grass and chasing bugs until they were ready to go back in and have a nice, long nap.
I didn't have my phone with me yesterday, sadly, but this morning I got pictures! Max realized she's strong enough now to jump to the ledge of the brooder when the top is up, and Jack figured it out after watching her do it a few times. So I ended up with them both jumping onto my shoulders, haha. So photo time!
(12 day old black sumatra chicks)
Max(closer) and Jack(farther) - You can see those long sumatra legs!
Jack, looking handsome as always!
My pretty Max
She's all nice and comfy
Jack is dozing off!
I wonder how much longer they'll be able to fit on the same shoulder?
They're growing shoulder feathers in now

I can't believe how quickly they grow! Max is already as big as our 4 wk. OEG chick! Jack is a wee bit smaller...I keep telling him he needs to grow more, haha.
