First off great work on getting this little guy up to health!
But I must stop you here! Yes I will agree, that some of these pet store employees are well how do I say this nicely"Aww mis-informed". Most are bound by store policy and have their hands tied. I have talked to a few local petsmart employees in my area ( it's one of the only places in my area that always carries my birds pellets), mostly the people who deal with the animals. When I was having trouble switching my sun conjure to a pellet diet and getting him to eat his veggies, one of the girls in the back gave me some really good tips and they worked. On a few occasions, I have complained about some of the enclosures and basically been told by the employees not to waste my time. They know that most of the enclosures are wrong, but can do nothing to change it. It's sad, but it all comes down to supply and demand. They won't supply if there is no demand!
