I think they can see the red light of the camera. Chickens can see ultraviolet light, whose wavelengths are shorter than visible light; I am not sure they can see infrared light - their wavelengths are longer than visible light.
This study says they can see roughly 419 - 570 nm
Ultraviolet light wavelengths run from 100 - 400 nm
Infrared light wavelengths run from 780nm - 1mm
This article on BYC is much easier reading, but less technical.
If anyone has more info, I would love to know more about their eyesight. The first article is pretty comprehensive in evaluation, but is also pretty technically written. I can follow the gist of it, but there are a few things that I just shrugged my shoulders on.
