Guinea hens usually let you know who they are about the age of 8 to 10 weeks of age. I introduce a Guinea hen into the flock only in a pen so the others can see her but not get to her.
Guinea cocks tend to fend for themselves and i introduce them at age 12 weeks after about 5 days in a pen.
The hens are penned for 2 weeks, age 12 to 14 weeks and then allowed to free range.
It is important to do this as the male dominate Guinea will attempt to mate a young female and this can cause injury.
It is REALLY important that your young ones pick up an older Guinea for a bud if they are the only ones introduced.
Guinea birds can be rather nasty to one another, but I have never seen one kill or mame thier brethern. This does not mean it will not happen.
Guinea birds are extremely resilent to desease and external wear and tear. They are hardly ever seen walking, it is a trot or a run and they are
EXTREMLY good flyers.
BTW, I band my female Guineas when I find out who they are. I do grab one every once in a while at roost and give them a once over for mites, lice and scaley leg
mites. I also check for missing feathers during mating season and check the band. If I find a Guinea with missing feathers and no band I know they are being chased
by other males. I ususall pen these ones so they will not get injured and usually they are good when the next breeding season comes along.
If you see a pair of mailes chasing each other, do not fret too much unless it goes on for a long time. You would think the one being chased would just go to flying off, but I think it is a game. I watched a pair in a full out run go around the barn about 20 times and i finaly broke it up as i saw they where patting really heavily.
Watch your birds and you will learn how they operate.
