My condolences, he looked like such a sweetie with a long life ahead of him. When I read the update last night, my heart sank and I had to sign out cause I was so angry. NOT at the OP, but at the breeder.
I've had a day to calm down, so I'll say this.
I understand that no one but the OP knows the entire situation and I acknowledge that. But there is a much larger issue here and its not just this breeder, but many others- I hear about them on Craigslist all the time. My friend tells me (I had to tell her to stop doing that cause I couldn't bear hearing it knowing I can't stop it).
But far too often breeders sell unweaned birds and birds that are too young to be sold. While MOST breeders are responsible and caring providers, to me one bird dying because of irresponsible breeder is one too many. In Maine, the rules regarding birds are VERY strict, Maine has some of the toughest animal welfare laws ESPECIALLY regarding birds (however, the penalties are a joke, IMO). They are required to provide access to food and water 24/7 which has to be changed every day, they are required to have their birds in a certain temperature range as well as having to provide at least a certain number of hours of light each day. While those laws do not apply to breeders, but rather retail sellers, I'd hope there are some regulations about that.
When I got Skittles, I received a certificate of health from the store which contained his birth information and his last vet checkup. Both required by law. I was provided his breeder information ONLY because the pet store offered it because the breeder requested it. I know for a fact that Skittles breeder was a VERY loving and caring provider. In fact, I still email her updates and new pics still. I did so just a month or two ago and she lets me know how healthy he looks and how much she appreciates the updates. Why can't all breeders be so nice?
I want to reiterate that my DEEPEST condolences go out to the OP and the poor bird as well. But I won't say what I think of the breeder (and other breeders who are like that one because that I KNOW would get me in trouble here, and I don't want that. I like it here). It was just seeing those adorable pics and knowing what happened broke my heart.
Okay, now that I've got that off my chest I feel better!
I wish the OP the very best with their new bird and many happy memories.
