So I have a question, When I hold my Seramas on my lap at night under their blanket for cuddle time, (doesn't everyone do that with their little chickens?) at least three of them make little trilling sounds. I'm not sure what it means? are they happy? are they ticked? what does that little trilling sound mean? They don't do it all the time, just every now and again while they are being cuddled they make cute little trilling sounds. I just wonder what it means. Anyone have an idea?
