Hello!
Birds often symbolize goals or ideals as they are something we usually have to look up to. This is true even if the bird in the dream is on the ground or dead.
I wonder if you and your boyfriend are trying to conceive, as the pets are wearing cloths and being cared for as if they are infants.
The idea of looking for a place to shower shows the desire to cleanse and purify.
The sick rotting bird seems to also point in this direction.
To smell something in your dream, indicates your past experiences and feelings you associate with that particular smell. Your dream is trying to convey a feeling with a familiar smell or scent. Alternatively, the scent may be part of your real environment which you have incorporated into your dream.
If this is about having a child, this bird could be pointing to a past experience that was disappointing. Perhaps because your body isn't healthy enough to have a child.
The child idea may be all wrong, but you can insert any hopes, dreams, or aspirations that apply.
Hope this is helpful.
