I have two bantam/Ameracauna mixes. One hen and one Roo. My hen hatched out three little fluff balls in August. They are now 9 weeks old and I've noticed for the past few morning's one has been making an odd sound. It's three notes. They don't sound exactly like a crow but being little maybe. They are very close to a window where they can hear my other roosters crow. Is it imitating what they hear or is it a roo?
