The issue with aspirin is that it thins the blood and that's not a good thing if there is bleeding. Since there could be internal injuries, and we haven't seen pictures yet, I would hold off on that. At this point, cleaning and flushing out wounds, treating for shock, are the most important things. If you have electrolites put that in their drinking water. Try to get them drinking and hydrated, dip their beaks if needed to try to get them to drink. Put them in a safe, low light, warm, quiet place. Sick or injured birds can become hypothermic easily, so warmth is necessary. Fluids should be room temperature to slightly warm. If a bird seems cold you can put towels in a dryer to warm them and then roll them and put them around the bird. So sorry this happened. It never happens at a 'convenient' time, always at the worst time it seems. They can often recover from some pretty horrible injuries if there is not infection, internal injuries are harder to know. Sadly dogs tend to squeeze and shake.
