2 wk old chick with nasal runniness and congestion

[CGilbert]

My 2 wk old Silver Grey Dorking chick has been a continuous chirper, so I thought it might be breed specific. The only other chicks I hatched were White Leghorn/Delawares.
A few days ago, I noticed she had pasty butt, but it didn't seem to be clogging anything, just extremely poopy and dirty. I cleaned her up. Yesterday, I noticed pasty butt again, and noticed that her nose was clogged. I got the clog out, cleaned her butt up, and she was still breathing through her mouth. I put a drop of water on one side of her beak. It went through her nostril and she drank it, so I knew it was clear (did that to both sides). Then she started breathing through her nose. I put her back in her brooder with the smallest of the leghorn/delawares (the rest of them are in the grow out pen). Then last night, her butt was grubby again. I cleaned it again. Then this morning, her butt was pasty and her nose was clogged again. I cleaned and unclogged.
Other than these two symptoms, she seems completely normal. Energetic, happy, eating, drinking.

Any suggestions?

I'm noticing it's more runny butt than pasty.
Any help?

Anyone??
Cull?

Maybe culling will be the best choice if your chick isn't getting better...what are you feeding her? Is she seperated from the other chicks? Do you have molasses/electrolytes in her water?

She's got one other chick in with her, but everyone else was moved a week ago. It's only been going on for a little less than a week. She's still on chick starter which is what all the chicks are on.
No molasses or electrolytes in the water. Should I put that in?

Now my chick with runny butt is in a separate tub. Her poop looks normal, but she is definitely runny in the back end still.

Ok, the first poop looked normal, second one is getting runnier... and discolored. Looks more like ceacal.

Yeast infection/thrush.
Adding copper sulfate to the water today.
After switching her brooder to something that didn't have pine shavings, her nose is doing better too.
