I have 2 little guineas that are starting to try out their voices...only heard (what I believe to be just one I've heard) the calls 2 or 3 times now. So far, the biggest one was acting like a hen...then the next one did. My luck they're both hens...or both cocks. Ugh...I have bad luck. Anyways, a friend of mine has full grown ones so I've heard the difference in the calls when they're full grown. My guys are probably...3-4 months old now. They still chirp like chicks, but their chirps are starting to change and get more like the grown up clucky chirps. We had some hunters over the other day and one tried calling out to let me know they weren't here before but they were now! Anyways it was the chiiiiiichhiiiiiiiichhiiiiiiiiiii (like the male warning call), now I know the females can sometimes make the same noise...but I'm wondering where they're testing out their voices and getting a feel for them...its possible for them to call with both sexes voices? Guess I'm just so excited for females I'm praying to everything possible they're female and male. See they're still young, this picture is from the same day, about a week ago. Noticed today they're JUST starting to get their crowns a little bit, just little buttons so far I find it really neat to watch the transition! Only ever having older ones before!!
