I have an almost three year old chicken who has had impacted crop three times since January. It was cured in six days the first two times but now she will not drink any water.I don't think she likes water and that she isn't drinking enough and that is why she keeps getting it. I have slowly broke up the impaction and now it is the size of a golf ball.I am now at a stand still because she will not drink and is very picky. What can i do to get her to drink water now and when she gets better? Also do you know what else might be causing her to get the impaction?
