I have fed my chickens lettuce without any problems for years. Ducks maybe different, but it could have been coincident. I don't know what either green could contain that would be toxic to an animal eating it.

The only thing that I can imagine being a problem with greens, is the pesticides and herbicides that are applied. Or, maybe the toxic sludge fertilizer or diary farm antibiotic-laden manure sluice they spray on it , which the plants soak up (this was the source fo the crazy e.coli spinach disaster a few years ago- the spinach soaked up toxic levels of e.coli). It's hard to beleive in this day and age that there's still lots of folks who are still under the beleif that they can wash off the toxins. Sadly, it's not possible with the amount of crap they are using to grow food- it soaks into the soil and uptakes into the root system. (Remember in 4th grade science how we soaked white carnations in colored water?). Iceberg lettuce, I know, is particularly high in tin , due to pesticides.[/COLOR]

BTW- since we're on that topic- does anyone else use EWG;'s "dirty dozen" and "clean 15" for their produce buying guide? I've been using their guidelines for years, when I can't buy everything organic, I atleast avoid the worst of the toxic produce. [/COLOR] [COLOR=800000]

There are a lot of different compounds and molecules in all foods, some beneficial and some not so great. I have never researched lettuce, but I suspect that washed lettuce is pretty benign, and mostly good nutrition.
Spinach is a bit controversial. It contains oxalate, which binds with calcium, making it less absorbable. Calcium, magnesium, Vit D are all interconnected as are probably many other compounds. All can effect neurological, skelotal, and organ developement.
Depending on the the source info, it is considered either the most poisonous food on the planet or it's the safest. Of course the truth is probably somewhere in the middle. That unless you are eating large quantities it is safe for you and your animals. Baby animals are more sensitive to the effects of foods because of their smaller body mass, and larger intake.
Russ- The Dirty Dozen list is good to be aware of.
Washing your food thoroughly, handling foods carefully and cooking properly is always a good idea.
