Hello. I have a 1 year old hen who has been acting sick, lethargic, and has been continually pumping the tail/vent area. Two days ago I was able to extract a kind of membrane looking liquid from her vent. I thought she might be egg bound so I bathed her for 20 minutes and separated her from the flock in a peaceful area. I placed some other hen eggs in her enclosure to inspire her to lay, and she just laid a shell-less, yellow rubbery egg with what I think may be a misformed shell? (Image attached.) Has anyone seen anything like this before? What might be the cause/treatment of this? We did just undergo a two day heat wave, but this seems extreme to me. She has always been a great layer.
