I don't know if I should be worried

not sure if this is the thread I should be posting or in emergencies but I was out with my four chickens and decided to share my string cheese with them after I opened itabout three fourths of the string cheese was left when my Buff Orpington chicken jumped up grab the whole thing took off running when she stopped she swallowed the whole string cheese thing in one gulp afterwards she went and ate their nightly dinner that I give them before they go to bed she's acting fine but should I be freaking out she's almost 3 years old
