Is the lobelia flower poisenous to baby ducks?

Maybe the chemicals in the pool are killing the ducklings. This is a question to ask one of the sponsors of this site- just answer- it costs a little bit- have you thought of replacing the flowers with another type--personally I thought that only dogs and cats killed ducklings-they're pretty hardy. A cat just got into my dove nest-ate the 2 babies during the night. Sounds odd, but my hounds were upset when they found mama-came in and showed me. Animals think that you can make things right. Sorry about the loss.

I think the pool is the culprit too. Ducks drink that water and swim in it. Be careful as their poop brings salmonella. You can get some chicken wire around the base of your pool fence to keep them out. Kinder for them.
