My 7 month old RIR Cornelia Marie has a very distended crop. I noticed this yesterday but I don't know how long it's been going on. It's not hard at all, but soft and squishy and makes a gurgling noise when I massage it. She pukes up a little but there is no foul smell to it. I have tried to massage it down a few times yesterday and this morning it's still huge. I offered her some bread soaked with olive oil but she doesn't seem interested in it at all. I have separated her from the other girls in a pen of her own with towels on the floor so she won't eat any bedding. She has plenty of fresh water. What would my next steps be? I'm thinking I need to put some olive or mineral oil into her crop but I've never done this and I don't want to put it into her lungs by accident. Any suggestions would be helpful. My vet owns chickens so I could call her if it's necessary.
