Our ducks have an inclosure inside of our fenced yard, but during he day they are allowed out to roam the whole yard (their pond, food and housing is in the inclosure). This year I am planning to border the whole yard with flowers and to put in a very large raised bed to fill with herbs and lettuces. Is there anything I shouldn't put in?! Anything that would be toxic to the ducks? The raised beds will be high enough that the chubby Pekins can't get up to it, so anything that might be harmful can be interchanged with the lower stuff. Thanks in advance for any info or advice!
