Hello again Chito. I apologize for the delay in getting back to you. I had to go the the vet this evening with one of my own birds. First off, I highly doubt there is anything going on with your birds that will affect your or any other human's health. The bird/parrot diseases that are zoonotic makes bird very ill and you would know if you had something going on to that degree. Of course I cannot diagnose for you from long distance but my best educated guess, based on all you told me, is that you have been very lucky to have any any normal hatchings from these birds. The only birds that can ever be counted on to be genetically sound as breeders and can be guaranteed to not be related are birds that come from the most reputable of breeders. Unfortunately that does not include birds from pet stores, swap meets, flea markets and so on. A really reputable breeder with top notch birds will not have to resort to those means to sell a bird. Also, they will not sell them that way because they are more interested in making sure the birds are getting a good home rather than making money being their top priority. I don't mean to sound like I critical your friend but if he has "all kinds" of birds and he is selling them at swap meets, he is not acting as a reputable breeder would act. When birds are not of the highest quality, genetically speaking, and when you cannot be guaranteed they are not related, somewhere in their family tree, they should never be allowed to breed. I am always having to caution folks who by their birds from pet stores to have them as pets only and not to breed them, for the exact reasons you are seeing. Deformed chicks are much too often, the outcome of breeding that type of bird. It's not the birds fault and it's not likely it is any kind of illness or disease. They are simply not suitable as breeder birds. However, the fact that they are outside and being exposed to all the airborne disease and parasites that are carried by wild birds, you certainly cannot rule out the possibility that they have some health problems added to their inferior genetics. My best advice, for the sake of the birds, is to have them checked out by a good Avian vet for any illness or parasite they may have picked up outside. My next advice is to never allow these birds to breed again. You can't separate them, now that they have bonds with each other and of course you can't stop the breeding. But you can discourage the laying of eggs by removing all breeding boxes and taking other steps. You can also gently boil any future eggs that might be layed anyway then return them to the pair and allow them to tend to them until they give up and abandon them. If you just take them a way, she will likely keep laying trying to replace them until she destroys her health, becomes egg bound and dies from that or both. If you really want to be a serious and successful breeder, you need to allow the birds you have to become pet birds. Maybe even find good homes for them with folks who will adopt them, in pairs and who are not interested in breeding. Then search out a truly reputable breeder, buy a pair that are guaranteed genetically sound and unrelated. Do not leave them outside. Bring them inside in a nice cage where they will be protected from all those outside dangers and go from there. I realize this is probably not what you wanted to hear but I think you wanted the most honest and helpful answer I could give you and that's it. These birds are just not breeder birds and there is nothing you nor anyone else can do to change that. If you have any more questions though, just let me know. I'll be glad to help further in any way I can. Patricia

Where did you buy the Conures? Are you going to bring the birds inside the house instead of having them outside?
