The Nattering of the Birds
Oddly, this seems to happen with other birds as well. We got some baby chicks a couple weeks ago and they were living in a large cage I built for them. It's easier to keep chicks in the house for the first couple of weeks where you can monitor their food, water and temperature. They were monitoring the length of the day for us and every evening just before dusk they would start talking like the birds in the trees talk to one another. They shared their days with one another, quite vocally for about fifteen minutes before it got dark.
We have since moved the chicks into the chicken yard and I have to admit I do miss their nattering every evening. I'll look forward to the next batch of chicks that will be delivered to us in June.
