That would be pearl Grey and a young one too. a year or younger. Helmeted Guinea fowl are what you are going to find domesticated... No matter the size. If you need to put some weight on try adding Cat fish pellets to their Flock raiser feed.
The ones that are loudest are usually the Hens.... they say Buck-Wheat Constantly... over and over and over and over.... and over again...

They all sound like squeeky hinges when they are in a flock and discussing some trouble to get in to.... LOL And they all Chatter loudly at something they find new or out of place in their world.
The blue fades as they mature. the first year is when they cause the most mayhem... come spring there will be alot of chaisng about and showing off for the girls. but they usually pair of and life settles down once the hens start laying. I found mine to be reaonably quieter their second year on.
But then I enjoy their noise and antics. it lets me know where they are... Out in the rocks usually ... I holler Treat treat treat and they will come flying over the house land on the roof to see if I mean it and then come down for dinner.
