AGAIN - Why is this happening!?!?!?

Again I lost a bird. It was fine this afternoon. Tonight I find it dead on the cage floor. SAME kind of parakeet. The blue one. Now Jolly AND Jolly 2 have died.
I check the body for damage and found no blood, no missing feathers, NOTHING.
This is more than an unfortunate coincidence. I am CONVINCED the pied is responsible for the death of both birds.
I don't get it though. They got along fine. Had seperate water dishes, bathes, and food bowls so they didn't have to compete for anything. I had double of the toys at each ones perches throughout the cage and yet again I find a dead bird.
The pied HAS to be the killer.
Is it possible to have a parakeet that appears to get along with other birds and then kill them? Why can't I find injuries?
This SUCKS!

Steve, first of all I'm really sorry this happened AGAIN to you and your family. I don't think the pied is responsible though. If it was inflicting fatal injuries on the other bird, you'd definitely see it. They go after the face, beak and legs. It's possible that the pied was bullying the other birds away from the food, but I honestly think you would have noticed that too.

Was the replacement bird purchased from the same place as the original that died? If so, they're likely siblings since they looked so much alike. It could very well be a congenital defect from inbreeding. It always seemed (to me) that if there were such defects that they wouldn't pose a problem until a few weeks after the birds weaned, say around 10-12 weeks. We had a pair of keets that were siblings *accidentally* clutch on the cage floor at an early age. The babies hatched and grew up just fine until they were around 10 weeks old. We kept them because we didn't want to sell birds that were inbred, but they all dropped dead--one after the next--within a few weeks. I'm just saying it's a possibility, especially since you seemed to have ruled out any other likely causes.

Sorry once again. Don't let it totally spoil the idea of birds as pets for ya.

Yes. Both blue ones were from the same place.
Actually we bought the second BECAUSE it looked so much like the first one that died.

Aw jeez Steve, I'm so sorry..... I'm sure it was nothing that you could have prevented....

We had a female finch whose male partner never lasted more than a couple of months with her....never did figure out why, and after going thru a few males, we just gave up. She has passed now (of natural causes, lol) and are kind of contemplating a new pair of finches, but just haven't found the right ones yet.....can't find any of the type I'd like to have so for now, we are "finchless"....

hope it isnt bird flu

Sorry to here of ur loss though , i know whats it like, it aint plesent to say the least .
