My 2 week old Black Australorp has been straining to poop for the past 2 days. Each time she tries to poop, she chirps frantically, the poop doesn't fully come out of the vent, and the vent majorly begins to bulge, like it's possibly prolapsing?? I have to help her with a q-tip and/or warm water to get it out. She eats a lot, but I don't see her drink as often as her siblings. It seems so painful for her to poop and I'm not sure what's going on. I gave her some yogurt today and I've given her some water and olive oil by a dropper for her to drink, but no luck. I've also tried putting a little Vasaline around her vent to ease the poop out, but still no luck. I feel like if I'm not always around, she won't be able to get her poop out. I did give her some egg for the first time a few days ago, but I made sure to give her some grit with it.
Any advice to give or any clue on what's going on with her?
