Chickens are just like any other animal, so they are probably wondering where 'their' family is and who these strangers are... :) They are actually quite intelligent and once they get to know you, should bond to you quite well.

You have a secret weapon...food. Chickens are VERY motivated by food and are always foraging for it. Once they learn that YOU are a Good Human who brings Good Things To Eat, they'll love ya. :)

If you want more info on what to feed and how to keep and care for chickens, you can see my website, here:

Hope it helps, and enjoy your chickens! :)
