We do not buy breeders for the purpose of resale.
Sometimes we have a pair that will not breed and produce for us.
Some birds do not feel safe in the environment that we provide. We will work with these birds for 2 or 3 years and do all we can think of to get them comfortable and laying for us but at some point we make the decision to sell them to someone else who might have the "key" that works for the pair.
We will not sell 2 boys as a breeding pair. We've experienced that on a few occasions and feel strongly enough about it to not do it to someone else.
