I'm worried about one of my girls having an impacted crop. My Americauna has quit laying. The last egg she layed was quite a bit smaller than her previous eggs. She seems to be acting normal for now. We have dealt with her having an impacted crop before (about 2 months ago). She made it through that and it took her a while to start laying again (probably a month). I'm worried we're about to go through that again. She is one of 2 chickens we have. They are both 8 months old. Should we start treating her now or should we wait to see if she starts showing symptoms of an impacted crop again?
