Well, I am new to this site....but glad that I found it.....We have a 3 birds, a sun conure (Damien Andrew), a green quaker (Donovan Anthony) and a cockatiel (Daisy Ann). We also had another cockatiel (Duchess Anya) who sadly passed away maybe 2 months ago. We are fairly new bird owners. Almost a year an a half. Here is the situation.....we have 2 cages, and the birds are able to openly roam between the two cages. All the birds seem to get along. However, the boys (Damien and Donovan) can be a bullies at times. There has always been enough room for the girls to get away. Today, my daughter brought Daisy to us and showed me her feet. It actually looks like her toenails are missing!? Another of the toenails is obviously falling off. She doesn't want to put weight on the one foot where the toenail is falling off. It is clear that it is not a fresh wound. We are wondering if the boys bullied her and actually bit her toes off? Not sure that a trip to a vet is necessary because of the healing process. We have actually seperated the boys cage into another room, so there is not the chance of bullying anymore. Thoughts would be helpful.
