The mother duck will be upset, but she will not try to interfere with your rescue. A helper would be great, ducklings will move in a group to a corner, where you could throw a light cover over them, an old pillow case, light towel. Once their eyes are covered, they will be less afraid. Gently pick them up from the back, using both hands to wrap around their wings. Hold firmly without squishing. :) You could put them in a box, a plastic crate of somesort until all are caught. Return them to their mother, and they will happily move on. If possible, be quick, don't make too much noise, put everyone together to lessen any stress that humans cause them. Thanks for helping.

call the aspca or humaine society and they will send someone out to do that.

Call the American equivalent of the RSPCA

So there's some baby ducks stuck in the pool outside our apartment building. The pool isn't filled and it's not cared for ever so it's not likely anyone will be around to get them out. Any suggestions for me getting them out?

I don't own a net, and I'm worried the mother will think I'm attacking them. However the babies don't have access to grass or anything nutritious they need.
