Chickens going really pale in the face

[Jetblack2004]

A few of my RIR chickens have gone really pale in the face and I'm not sure what to do. The other day on some of our Light Sussex chickens I found lots of little lice so I've bought some spot-on stuff to put in all our chickens. I'm not sure if the chickens are going pale in the face because of the lice or because of something else. I'm worried they are going pale be a use something is literally taking the life out of them. Please help.

Thanks
