I have an adult chicken who is struggling to poop. Yesterday she had a prolapse and it was put into place by my vet (I'm a new chicken owner and did not feel qualified to do it). They told me to watch and make sure she is pooping okay. She seemed to have some thinner poop that was passing without any problems, but tonight I can see she is struggling to pass what appears to be more solid, but normal, poop. What should I do? Is there a way I can help her pass it? Her vent is open and hasn't prolapsed again, and I can see the end of poop starting to hang out. I can see her muscles trying to contract to get it out, but the muscles are too weak right now, I think.
