moaning and chirpy hiccup sound - sick or getting ready to lay egg?

[srosedahl]

Our 19 week old buff brahma started this moaning sound mixed with little chirpy hiccup type sound today. She doesn't sound wheezy or sick otherwise. Not sure whether it is the beginning of a respiratory problem or related to getting ready to lay an egg??? They just went on to their roost for the night and she is not doing it as often. It is not with each breath. Thoughts?

I think it's just a getting ready to lay vocalization.

She's just talking/singing to you - normal vocalizations in my experience.
