We only have two red stars in our flock, they are amazing. One comes up to be petted, the other rides around on my shoulder when I'm outside. These two girls hands down beat our buff orpington ladies in the friendly department. They are sweet and lay without fail, also have not gone broody like our buff orpingtons. Ours even beat out our silkies in the friendly department. They are great foragers when allowed to free range, I nearly always get an egg a day from them. They are also very curious and always want to know what we are up to. They will follow us around the yard like puppies and let our daughter pet them. The only con is if you don't want to give them attention at any time they will demand it. They also very loudly announce to you when they have laid an egg. Every time. Sometimes for 5 minutes. They can be as loud as a rooster crowing in the morning. Our red star girls will run through the back door into the kitchen if they feel we haven't fed them soon enough. Ours have never failed to give us an egg since they started laying this summer. They really have opened our eyes to hybrid breeds. I am glad we have them in our flock. They have laid rain or shine, hot or cold weather, since they began laying this past summer. They also vary enough in looks we can easily tell them apart at a glance, unlike our other hens where we have to look very closely because they are so similar.
We initially were not impressed, as our very young daughter picked them and we had no idea what they were until they feathered out. Now? We love them. Easily the favorite of the chickens in our flock that include Gold Laced Wyandottes, Buff Orpingtons, and one Rhode Island Red. It'll be a hard choice between Red Stars and EEs when we need to add some fresh, young egg laying hens to our flock.
The only bad parts are the demands and the egg alarm. They demand attention. Where our other birds are content to have nothing to do with us as long as they have food, our red stars are in our business 24/7. They just have to know what's going on. They also very loudly announce they have laid an egg. Forever. Lol. It goes on forever, they love to do this even more than our RIR. I used to always run to the backyard thinking something was wrong, now I know it's just the egg alarm so I can empty the nest box.
