My RIR swallowed a 2 foot section of string attached to a feeder .I tugged on it slowly and managed to get it out . I was worried that poor hen would die so I didn't check online for info . Now it seems I may have done the wrong thing . There was a large knot in the end she swallowed so perhaps I was lucky to get it out . She seems a bit off . She drank some water but is not eating .Any suggestions ?
