Neighbor spread poisonous grass seed

[millerbeachindiana]

My neighbor spread seed which is poisonous for my birds
They ate quite a bit before chasing them off. Then he decided to tell me.
What do we do? I'm afraid to give them water. This seed has a coating.
How do i prevent damage to my birds? We're trying to get them better contained.
Currently we have a low voltage fence for a run.
They fly right over it. It proves effective for preventing ground animals from getting in, but not contain the birds. Currently, I have most of them in the coop. Some are loose.
Can I give them Water?
Should I clip their wings?
Build a new fence ?
Please help.

It's good of your neighbor to have told you so you know what they injested. I would call the company and ask what hey suggest. You can also do a molasses or Epsom salt flush... Last resort would be to try and empty the crop....
