Thank you all!
I know my pictures aren't clear, I'm going to try and get better ones when I next candle.
Eve - thank you for your advice! Funnily enough I have just started a little newbie chicken blog

I'm becoming rapidly obsessed and I don't even have any chickens yet! Lol
I have yet to speak to the breeder as I missed his call but I'd be interested to know if it is a regional variance as two of the three orps are speckled/porous like these and neither promising!
Kimbo - please comment away! This is my first time ever doing anything chickeny so I'm the least knowledgeable of anyone!
Chrismahon - thank you for confirming my suspicions. No I haven't used sanitiser

I'll learn for next time. I wash my hands before touching them of course, but only with normal handwash.
I know I shouldn't be handling them too much but I'm loving the learning process of seeing how they're doing. Plus I'm now panicked one could explode at any minute haha
