Hm well the shampoo I use isn't blue it has sort of a pearlescent look to it. I think the dilution directions are so that it lasts longer. I don't think it will causing burning to her. If anything, it may cause it to colour her feathers blue if you use it without diluting it. Although, I'm not 100% sure!
Do you have an old washing bottle or even just a drink so bottle? I'd put some in there and premix with water ready for use just to be safe. If it was me, I'd just put a cap full in, fill the bottle with water and shake, ready to go!
Haha those famous words 'supposed to be a sexed pullet'

at least he's still got a pretty name!
Yes Audrey likes the bigger chickens for some reason, she's more feisty. She's never sat or hatched eggs before but I think she'd do fine! I do have PomPom who came second in the show sitting on 5 eggs now. She was a determined broody so she got what she wanted in the end.
I'll send you a PM later on and you are free to look through my photos. It's still I work in progress but I'm getting there!
The Quails have already gone to a loving home as pets. They called one Toe Nail...
They were older than in the photo, all fully feathered little white fluff balls!
Yes males do fight, even worse than roosters in my opinion. They do a kind of slow torture of one another. Picking away at the back of other males heads and end up scalping them.
Some do get along but it's always safe to just keep one male or non at all
