I'm brand new to having chickens, we've only had our 5 Ameraucanas (rescued) for about a month now. In the mornings, right after I let them out, Chickpea (the one in the video) does this vocalization really loudly. The other ones do it a little bit, but not as often and not nearly as loud. I'm hoping it's just a "give me my morning scratch, RIGHT NOW!" and nothing bad. Any help identifying what this means would be greatly appreciated, thank you! Note: the sound I'm asking about starts 15 seconds in, not the ones she's making at the very beginning.
