My girlfriend Maria and I have 7 birds all together. We keep all of their wings clipped. They are caged at night and during the day are able to roam around in their large bird room. The problem we are having is with our senegal "Sophie", not sure of sex. Sophie is bonded to my girlfriend Maria and pretty much hates everyone else. The problem is that she is biting Maria a lot lately and normally she didn't. In response to these bites Maria will put her in her cage for a time out. It worked in the past when she would only bite once in a while. When Maria goes to put her down she doesn't want to get off and will bite or try to bite. So she started using treats for step up's and step downs. We've changed up the toys and rearranged the bird room but thats not helping either. She's about 4 years old and we've had her for almost 2 years. Any suggestions would be great because we don't know what else to do.
