Last Saturday (8 days ago) we got six red pullets from TSC. All was going well until about four days ago...my daughter noticed one of the chicks (Pearl) had a very swollen crop. After doing a little research [these are our first-ever chicks], we narrowed it down to a crop issues, either sour crop or an impacted crop. We are leaning toward sour, since it's not hard. The swelling has not gone down over night at all. The chick continues to eat (which may be bad??), and otherwise acts like the other chicks. Yesterday we--by this I mean my husband --held the chick and massaged the crop for a long time, and also held her upside down while massaging it, trying to get her to vomit up what was in there. That didn't work. This morning, my daughter said the chick 'threw up' a little when she picked her up; she also tried massage but to no avail. Is there anything else we can try?? We hate to lose this chick, especially if there's some way we can help her.
