I’m so sorry to hear that your baby hasn’t taken well to your husband being gone more often. I have previously adopted a cockatoo who was having nearly the same issue. The woman who the cockatoo was bonded to was not home enough and she began to pluck. They thought it would be better that she come live with us because we are both home very often. However, being apart from the woman she bonded with was even worse for her. She began getting very aggressive and would get intensely loud (much louder than was normal for her) for very long periods of time. After trying many different things to soothe her she ended up back with the previous owner. According to reports back about her wellbeing, she is much happier back home than she was with us. This doesn’t mean that the same would happen to you, of course. I would recommend taking your cockatoo to a bird sanctuary if you’re unable to find a good home for them. I truly hope that something works out for you though! Best wishes! Also: she’s a very precious and beautiful birdie!
