Hi, One of my chickens died recently and after doing some research I found out that it was an impacted crop. Soon after, 2 others died with the same symptoms. Unfortunately, another one is sick. I hope that one of you knows the best and most effective way to treat this. I have tried to give it bread soaked in olive oil, but it won't eat it even though it eats regular food well. All though I don't want to take such extreme measures, I would consider surgery. However this is the last resort. Any help is greatly appreciated. Thanks!
