Thank you for the inquiry, SunHwaKwon ! I know I have been remiss in updating, but non-guinea fowl life has been busy and the guineas have, but for two incidents, been well-behaved. In fact, I even took some pics of the guineas on Christmas Eve Day to post on here, but never got around to it.
Lucky for the guineas, we had a very green Christmas this year, and unseasonably mild winter so far. I found them outside our house pecking through the flower borders that I had torn up earlier in the year on Christmas Eve Day.
The guineas are now 7 months old. I have twelve and think that 3-4 are males and the rest are females based on observations of how they carry themselves.
I am feeding them Game Bird pellets, which leave less crumbs than the crumbles did.
Since the weather has been so mild, the guineas continue to free range. They have expanded their range territory to include the yards of neighbors several houses down our street. I live in a semi-rural area, so the houses are fairly spread out. Knock on wood, no one has come to complain. I even saw them joining a neighbor's free range chicken flock! I usually find them when I go out for my afternoon walk, and then we form a parade as we head back to my house, where they get treated to millet.
Despite hitting freezing temps at night, my heat taped water bucket has kept their water free from ice. The bucket has a top on it that keeps out all the dust, etc., so the water stays clean. I top it off every 4-5 days when I top off their feed bucket. The only other winterizing I did was to close the two windows in the co-op.
When there is snow on the ground, the guineas don't seem fazed by it. Initially, when it first arrived, they were hesitant to come out of the coop for a few minutes, but once outside seemed fine. It's funny seeing all the guinea prints around the yard!
The first incident happened at the beginning of December. I went to lock up the guineas for the night and noticed that one was missing. Being winter, it was pitch dark at 6 pm, so I got a flashlight and looked in the trees and around the property and called for the guinea, but nothing. The next day I drove down the roads to see if someone had hit it, but didn't find any body. I was also concerned that possibly some animal had snuck into the coop between the time the sun went down and I got outside to shut the door, but that didn't seem possible, since we have a motion light.
The next day, I went into the coop to do something while the flock of guineas was out in the yard, and was shocked to see my missing guinea in the coop! I was relieved to find it, but noticed it was acting funny. It just seemed to be a little off. To this day, it still trails behind the flock, several guinea steps behind and just seems kind of slow. The other guineas don't pick on it, but it just seems a little off. I have wondered if some kind of animal had gotten a hold of it, or if someone had hit it with a car and stunned it.
The second incident was worse. It was the middle of December. The day started off normally, but in the afternoon snow flurries began. The snow was swirling around and started to accumulate. This was the most snow we had gotten to that point, and it had continued into the evening. When I went out to shut the coop door, there were no guineas! It was cold, lightly snowing, and I was worried! I checked the trees around the coop and the property and no birds. So I changed into more heavy duty clothing, got a flashlight, and started walking down the road past all the neighbors houses. I found them next door, roosting in a few pine trees! The house next door is pending sale, so no one lives there yet. I flashed my light at the birds, tried calling them, tried bribing them with millet...nothing! I turned to go, and noticed that Slow (my guinea from the first incident) was sitting on the ground near the porch lattice. So I picked Slow up, and brought her back to the coop. I figured she had a better chance in there than as a tasty treat for some animal.
I felt so bad that night. All I could picture was an owl feasting on the birds. The next day, the silly birds were back and I was happy. I am convinced they got confused by the snow flurries and couldn't find their way home.
Since the ground is covered with snow, the guineas seem to fly more often. Twice I have observed the flock fly across the yard to get to the coop. It's really neat to be able to see them when they are flying.
