My hens are so curious! they especially pay attention to things that are different colored from green. (i have grass in my coop) mine don't eat lettuce or celery.
Wyandottes
My wyandottes have virtually NO personality. People who want to 'make a relationship' with their chicken, i don't recomend it! (especially if your only getting one) Plus, it's REALLY hard to tell which is which. But, they are REALLY PRETTY!!!
