I have a 3 year old hen who has been recovering from crop impaction surgery for a few weeks and very thin as a result. My worry is that although she is getting better and seems healthy she still weighs only 3.5 pounds and has had very watery diarrhea for several days that does not seem to be getting better. Here's a photo:

It looks typical of hot weather or not getting enough protein. I thought she just wasn't getting enough to eat at first but now it's been almost a week of seeing that she eats very well. She's had access to organic layer crumbles and free-ranged all day and I've been feeding her scrambled eggs, greek yogurt, garlic, and onions each day. Could the diet change cause this? I must admit I am one of those ignorant people who has yet to worm her flock, but I planned to do that as soon as this hen recovered. Could it be worms? Should I risk worming while she is still somewhat fragile? The diarrhea is getting more frequent! Please help my hen!
