They are 4 months. But I would feel bad sending them to you because, even if a gave them to you for free, it will still cost about $150 shipping to send you a trio of birds that we do not even know the history of, when you could spend that same money for some quality bred birds from one of the real breeders on here. Nobody knows anything about the Welp breeding. I am the only one on here that has their birds and we are all waiting to see what they will do when mature. It's up to you, but my advice is it to wait and save your money for something more certain.
