Is it because they don't see well at night?   Maybe because it's just instinct?   I'm just curious.   
I just ordered an automatic door for our ladies....they are 7ish week old banty ladies and have been kept inside their 10X12 hen house until now. I just want to make sure that when the light sensing device is set to close, they are all inside! How dark should it be before the door closes?
