Well, he's still with us. And we've named him. His name is Oddball, due to being referenced that way on the forum. lol So in a way, you all named him. He's still sleeping in the incubator for a bit longer (trying to keep the little belly tuft moist so he can finish absorbing). He may look like he's sleeping all the time, but any shift of movement and he's all over the place, chirping excitedly, eyes open, extremely alert. Very sleepy baby, which is understandable.
We set him in with the other chicks for a few minutes so that they can get some bonding, placed him in the middle of them and all seemed to huddle protectively. I imagine, given that things go well, in the morning we may be able to let him be with his siblings full time.
As for security, I've been pricing electric systems and they all seem to be pretty expensive. I'm currently flat broke.

My wife's parents sent us 100$, however, with the intent that we buy a 4 cam security system and some motion activated flood lights. I'll be shopping for those tomorrow. I may buy the electric system if we ever have a windfall that amounts to enough.
Much love to you guys, and thank you very much, once again, for your help.
Edit: My wife finds it humorous that the markings on his beak look like a little frowny face.
Also, an update on Magnus. He's been quiet all day, and refuses to eat.
I'm hoping it's due to the infection, and not trauma and grief. The first is easier to battle than the latter.
