About 10 days ago our 1.5 yr old layer had an impacted crop. We are new to chicks so called our vet for advice. We began oil in scrambled eggs which she ate readily. We brought her indoors and under a heat lamp and massaged repeatedly. Our vet tried to make her vomit 3 x over 3 days but she has never vomited to date. After about 6 days the crop reduced. She has been drinking all along and eating scrambled eggs, canned corn, soft baby cereal (pablum), meal worms (alive and dead) until today! Now she has lost her interest in all food. She still drinks water. On the 4th day our vet recommended Nystatin for 7 days 3mls twice a day.- today is the 5th day and she seems to be going downhill. We stopped the Nystatin. She won't eat today and her crop is flaccid but has water in it (squishy) We have been putting electrolytes in her water. She is less active and seems tired. Not interested in worms How can I tell if she is dehydrated? and what more can we do? Thanks for any help, all we are doing now is crying over her.
