My egg laying problems with Alex started a few months ago. She never laid many eggs, but she was starting to nest after Pretty Boy died. Alex, Danny, & Pretty Boy were my only tiels and they all lived together. When PB died Alex and Danny started trying to nest. I bought a nesting box and kept a close watch. Alex started to act really weird, but I thought it was normal. One morning she was lying on the bottom of the cage and Danny was super aggressive. I took her to the ER vet and she almost died. After x-rays and an IV and other meds they found two eggs stuck. They went up in side her and took them out, but I told them to operate if necessary. Now a few months later she is doing great. She lives with Evie and only sees Danny and Milton with daily supervised visits. She gave me a bad scare. If your tiel has a better diet then Alex HAD then everything should be ok. However, egg binding can still be a problem with a proper diet. Something to think about.
