Welcome from San Diego... Just a little bit of info. They are Guinea Fowl.... The males are Cocks and the females are hens.
Special needs.... it really depends on what you get Keets or adults. And if you have chickens already.
Guinea Keets require different starter feed than Chicks because the grow much faster and are much much more active. Game bird starter the highest protein you can get is recommended, otherwise they will be growth stunted and may have physical problems later. I used Purena Startina. The newly hatched Keets (from a hatchery less than 3 days old) are very tender need a lot of heat in the beginning. They will be the size of Bantam Chicks. But by week two they will be able to fly six feet up and able to perch on anything inside your coop. So Brooder cage or box needs to have a lid.
Adult Guineas will need to be locked up for at least six weeks so they can acclimate to the routine on your place as well as imprint on where home is. Guinea Fowl are incredible fliers so don't expect they will stay in the yard when you free range. My Guineas could fly up to the rocks behind the house and when they heard the feed scoop would come flying from the rocks up over the house to land in the yard.
If they were raised with chickens the only thing you need to do is provide them very high perches in the coop. So there wont be any perch hogging. I put mine up at about six feet there were a couple of roos that used to roost with the Guineas but for the most part they had the perch to themselves. Oh and best to set up a second feed station because When the guineas want a spot to eat they will shoo off the chickens.
They are not chickens so don't expect them to act like em. They are funny and silly and sometimes not the brightest bulb in the set. The most friendliest ones of my guineas will look me in the eye while standing on the perch six inches away but if I make a move to him he will leap off and run away. they have a very strong self preservation instinct which serves them well when they are out foraging in predator country.
My current guineas weren't raised with chickens and now that I have chickens they are very unfriendly toward them. So I keep my chickens and guineas separate for now.
Oh and don't worry about male to female ratio. In the wild Guineas pair off. The extra males will form a bachelor flock. The only time they get into really heavy duty sparing is when mating season starts. Then there's a lot of running and wings held up high behind their backs and feather pulling. Once they pair off then everything settles down for the rest of the summer. With only a few scuffles now and then.
They do better in flocks tend to pick on each other rather than singling out a chicken. Another thing to note when they find they need to protect the flock they attack as a group. All of them. They use wings beaks and claws and intimidation. A cocky Rooster would not have a chance. I have seen my previous small flock of five escort a coyote off my property hissing and charging at him the whole way. He kept looking back with an expression of "That's not Riiight."
As adults they eat the same feed, as chickens require the same amount of shelter. They nest in scrapes in the dirt in the wild and rarely will use a nest box. If you have some females its a good idea not to allow them to free range till they have laid their eggs. You don't want them to choose a spot out in the pasture or woods to lay their eggs because they will go broody and become fair game to predators.
This I am sharing from my own experience, here in Southern California. I am sure others will respond and put in their two cents worth, or more.... LOL.
