Ok, calm down now, lol. Depending on what hatchery those chicks came from, there is a fairly good chance that those Golden COmet chicks are not first generation. What that means is that they are only sexable the 1st generation, when the pure breed parents are mated and the first generation of chicks hatch out. If you cross a Golden Comet to another Golden Comet, the chicks are no longer sexable and white chicks could be female, and red could be male, or mixes of colors. I bought Amber Sexlinks last year at
TSC, and I chose 3 from the bin, 2 reds and a white. I realized after the fact that white was suppose to be male, and I kind of bit my nails as I watched them grow, afraid that I did indeed have a male, but it turns out I got 3 pullets. I kept 2 (one was mean), one red one, and the white one who grew up to be a lovely color combination of red and white. She lays eggs regularly and is one of the best birds I have, personality wise. So don't freak out just yet. Just cause they SAY white is male, doesn't mean that the hatchery is being 100% honest. A lot of them just cross the sexlinks and say the chicks are color sexed when they really aren't. Give them a little more time to grow and develop combs and saddle feathers before you start thinking about who to rehome. And if you got red ones too, you might want to watch them too as they might be roos as well.
As for how many roos can live comfortably together, I think the number of roos doesn't matter so much as whether you have enough ladies for each of them. I think the proper ratio is 5 hens for every 1 roo, so if you kept all 4 roos, you'd need at least 20 hens to discourage fighting and territory spats. I currently am short on hens as I lost some over the winter, but my boys get along nicely for the most part. They establish a pecking order, and each roo and hen has it's own special place within that order. Some of my lower roos are not allowed to mate, while others do all the mating. Some hens also will not let any roos mate with them. It's funny how that works. I have in my Bantam coop I have 9 roosters and 13 hens, and I have a minimum of fighting. I have only 1 roo that is a brat and starts all the fighting. He will be finding a new home shortly though! With him not around I think the rest of the flock would live in perfect harmony. If you decide to keep them all, and they turn out to be roos, make sure you have multiple feeders and waterers in the coop/run because each male will claim a territory near their food and water source. Mine will share the food and water, but certain birds get chased away from the waterer from time to time, like my Dark Brahma roo, so in their run I also have the duck pool which gets cleaned out daily, and he, and several others, drink from there when they are told they can't drink from the feeder. I have not had any cock fights bad enough to cause serious injuries, and in a few more weeks I will be introducing new pullets, just cause I need new blood in there. But they can get along. So relax, it's not panic time just yet!
