Hi, I'm pretty new to the board & chickens, but I have been reading everything I can find on here so I know more about my girls. I have 8, of different breeds, and they were 9 weeks old yesterday. So yesterday I noticed that the Dominique was not as active as usual. She was eating and drinking but wanted to spend more time by herself and under the light. I watched her all day and she just stayed the same. This morning she had a swelling in the crop area that is soft and fluid filled. (or at least that is what is feels like). If you massage it it girgles. I took her to the vet (who is not real up on chickens) and he thought that it was her crop. He couldn't find anything that felt solid or rigid and said to wait and see if it resolves itself since it is so soft. He also said to let her continue to eat and stay with the rest of the girls for the next few days to see what happens. Does this sound right? And since it is not hard should I still give here mineral oil? And how serious is this? I am really worried about her. Thanks for all your input.
