Okay this is the second time this summer my girls have started clucking at night. The first time was about maybe a week or two ago around 11 at night. It was totally dark outside and I had just hopped into bed when I heard her go off. She was clucking like she was going to lay an egg. So it wasnt a scared cluck or angry. I went out to see what the deal was but didnt see anything out of the norm. The second time was this evening, only much earlier. It was just barely dark outstide, but they are usually quiet by then. But I heard that same type of clucking so I went outside to check on them and one that was clucking was out in her run and the others were all perched for the night. Are they looking for a mid night snack perhaps?
