Hello, My hen, Chatty, has had this thing going on where she is leaning back like she is going to fall over. I looked around the vent area, and found below the vent, a big red ball. It looks like her crop, but bigger, and redder. I'm posting a couple of pictures for you. I'm sorry is they are gross for you, but this is the only way I can let you see what is wrong with her. She stands like this, as if the big ball is so heavy it causes her to lean like this. This is the big red ball, could it be feed? Worms? Eggs? Do you have any idea what is wrong with her? She doesn't really run fast, but will come when the feed is being poured. Is there a way to get rid of this? Thanks!
