I generally keep my chickens out of my vegetable and flower garden most of the year, but let them in after the first frost to turn over the beds, eat larvae, etc. I've expanded my flower garden this year and have lots of cosmos, zinnias, chamomile, sunflowers and other annuals I hope will go to seed and pop up again next year. My question is, if the chickens scratch up the flower beds, will they help move around the dormant seeds in a useful way or will they bury them too deep to germinate the following spring? (Obviously if we're talking sunflower seeds, they'll eat them up straight away!) Would it be better to fence off the flower beds? Thanks!
