So if seems like they are just simply calling (not crowing) - mine can hear us in the house when we wake up (dishes clanking, water running, chatting, etc.). I recommend to make sure they wake up to a full feed dish & fresh water, grass clippings to scratch around in, hanging greens etc. = something to keep them busy until you can get out there. My girl does that sound when she is bored & wants to come out. I only recommend leaving out feed/seed for the morning if your set-up is 100% hardware cloth so rodents aren't attracted to their breakfast overnight.It sounds mostly like the first one.
