Originally gold, silver isn't ideal for free range. I purchased hatching eggs. I have an aging small flock of gold. Last year I purchased more gold deathlayer hatching eggs and two, a male and female turned out to be lemon. This is a rare occurrence, talked about in very old German literature on the breed.
They are excellent foraging(prefer to find their own food), excellent flyers, excellent at predator evasion and excellent daily layers of 60+ gram white eggs, mine avg 300+ per year, even into old age. I don't find them to be nervous or flighty, they are rather friendly, curious, quirky and cute, but they do prefer not to be handled. The roos of this breed have been the most excellent flock protectors, they have the uncanny ability(I'd swear they can count)to know if a hen is missing, will search for her and bring her back to the flock. They are early maturing, start laying full size eggs at 4 months. Have delicious delicate tender meat if you choose to eat them. And have made a really good meat bird when I have crossed them to my Bruges for a quick growing meat bird. Included pictures of my golden/lemons
