Arielle, I think you have likely been very lucky so far as to not have impactions. I didn't realize hay could be a problem, either, until I had my first impaction & did a bunch of searching....then, took that hen to the vet, and the vet flushed out a HUGE ball of hay from her crop. I felt horrible. And I eventually had to put that hen down, because the hay ball was so large, it distended her crop, making it sag down, feed would get "stuck" in the crop and it eventually began to rot...I know it sounds like I'm being a major wet blanket, and I hope NO ONE else ever has the issue. Just thought it would be good to know of the possibility.
If you search here on BYC for "impacted crop" - there are several home surgeries that have been performed showing what was removed from the crop, and it's most always hay.
