Are these Sapphire Gems large chickens? My friend bought a blue hen, and I don’t recall the name, but it looked like the ones I found online. I don’t know if she still has it, because I don’t know the life-span, but it was bigger than her other chickens. Really gorgeous, too! (This was probably seven years ago.)
I don’t think that they will be exceptionally large, ours are about 9 months old at this point, and look to be mid-sized hens...
