If they are fully feathered and it is not to chilly at night you shouldn't need any light at all. It being dark at night is perfectly natural for them :)
That is not a brahma unfortunately, because of the single comb, wrong coloration, and absence of feathered feet. It also appears to be a cockerel (rooster) incase you were unaware. If you want a better chance at breed guessing I suggest you wait until he is full grown. Then repost with clear...
Riana shook the sand off her wings. A quick glance around led to the conclusion that she was in what appeared to be a cave. Further inspection revealed no exits or entrances. Where am I? How did I get here? And better question... how do I get out?
Hmmmmm... And what if I accidentally started a civil war among the outcasts? Then stopped it and now they are after the dragons? That wouldn't ruin anything, right?
This is Ester, named that because she looked like an Easter Egger chick when she was a couple weeks old. I wouldn't be surprised if she was an Olive Egger not a Cuckoo Marans.
Next hunt: name or breed that stars with F.
