My bird Max is having trouble holding on to his perch & sometimes it seems as a person thats had a stroke. His nails are the proper leghth. Sometimes at night he falls while in his cage. And when my husband gets him out he isn't grabbing on to him like he usually does. When my husband gets Max out he brings him to our bed because we don't want him to fall & brake anything. Max will flip over onto his back & its very difficult for him to role back over. Please help!!!
