This chicks hatched last week whilst I was away. I use an old fish tank as a brooder and the noise you can hear is the incubator and me tapping my fingers lightly on the glass, which they seem to go nuts for.

SIlver Dorking are 'sex-linked' chicks, which mean the males and females have different markings when they hatch, I think these are both girls but am not very good at telling the difference so might be completely wrong.

The video is red from the bulb that is used to keep them warm. (less info)
