I was very gently massaging her abdomen and think I could feel an egg but not certain. My man had read to never go into their vents w/ anything to avoid causing infection but I had read that in this scenario, as long as you're clean, wear latex gloves, and use KY, it's actually advised to do so to ascertain that the hen is eggbound. Alas, he was convinced we shouldn't so we didn't. All I know now that we could have done differently is notice the signs earlier and in worse case scenario, if the egg won't budge, it needs to be manually removed. The thing I learned to look for from suspected hens is whether or not they do proper poops. I can't overemphasize how happy I am today seeing all the other hens pooping today! Thank you very much for the kind words lazygardener. It was hard last night seeing the chickens on the roost pole; they actually left the gap for her, where she'd sleep each night.
