I just noticed some watery areas in my chicken pen. When I let my girls out to free range, I suddenly noticed it outside as well. Then I observed two of the hens squirting out water from their bottoms. Once it was just water, then a little wet poo with it and now it looks like it contains a light red pasty substance. Doesn't look like blood though. I gave them some overripe (not rotten) watermelon a little while ago. I'm wondering if that could be the cause? It's not hot out, and they have been eating. All are acting normally. Any clues? Thanks~
