I have a chicken that has had a butt that is poopy, like the feathers matted up. So I cut it all out when I realized it and that was that. Today I realized her crop was awful full compared to my other chickens so I automatically thought of the dreaded sour or impacted crop that I have managed to avoid so far. I went in and caught her and rubbed at it. I felt grain and a little knot that could have been hay or grass. The thing is as I was rubbing her eyes would start to close as if it felt good. Now, mind you I am not home on the weeks during the middle of the day when their crops are really full to see how the react when being held so this could be normal or not. I don't know. When she opened her mouth I didn't detect any overwhelming smell of sourness. So here is the question. Am I an overreacting concerned mommy OR is my concerns justified? Any help or opinions on this would be helpful. I would like to add that this evening when they go up I will check it and again in the morning. I thought to add some electrolytes and I have heard of giving ACV to them but I don't have any. And if I do find something else instead of ACV should I go ahead and give it to her without knowing for sure that is what it is?
