this girl has an insatiable thirst. I'll put out, in addition to their normal water, a small dog bowl and she'll drink the whole thing in about 5-10 minutes.
I'm pretty sure she's molting. Eggs stopped, weight loss, irritability (normal), feathers EVERYWHERE. I don't see any new growth like those pin feathers but she is showing all the signs. Aside from that she seems healthy. No lethargy, comb is nice and red.
But this thirst thing concerns me. Could it be a symptom of molting? I mean she gets violent over water. This is not normal for her.
