Question about lighting

[kerbotx]

I know light affect how much eggs any bird will lay, but I need something answered. Is it direct or indirect lighting? My coop gets over 12 hours of indirect light, do I need to make some of that light direct light? Thanks!

Chickens sense light with their brain as much as their eyes, so it doesn't have to be direct, or very bright. I couldn't remember the name of the gland in the brain that's responsible, so I had to google it - "pineal gland" - and found this interesting:
