okay, so my hen came into my kitchen and made off with an elastic band from the floor. she grabbed one before, i think she thought she found a very fine, albeit chewy worm.when i followed her outside, and grabbed her to get it, she swallowed it. will this harm her? will it make it out through her digestive tract? at first the other day when she made off with one and we caught it, this was funny, but now i am a bit worried .... i'd say the elastic was about 2" in length, in a loop shape ... make sense? not terribly large, but not an edible material. any thoughts would be helpful. thank you.
