I have a 4 day old silkie who is having a REALLY hard time going to the bathroom - she squats and holds her wings up and shakes and tries to shimmy around and as it finally comes out she peeps loudly. Her poops have looked relatively normal but larger than the other two silkies poos, and today they are chocolate brown and a little runny. She has had a pasty butt since she arrived on Wednesday and I've been cleaning it off several times a day. Today, it seems her vent is a little swollen or is maybe protruding a little bit. She is also eating a lot less today and her crop looks huge and feels soft and squishy. I tried giving her some olive oil just now - she didn't want anything to do with it so I put it around her bottom so she would get some when she cleans it off. She seems otherwise OK, running around and drinking fine. Any advice would be MUCH appreciated!
