Back from the Vet. Poor Lydia is a sick little chicken.
She's not broody, she's not egg bound, she's very unwell. Vet ruled out a number of things (worms, impacted/sour crop, etc etc). There are a number of causes for the symptoms she has, and it's impossible to tell exactly what it is yet.
She's on penicillin for the next 7 days (assuming, of course.....),I've got to weigh her every day to see whether she's losing weight, change immediately to Growers rations rather than Layers rations, and tkae her back to the Vet on Thursday morning for a review.
The good news is that she isn't in any pain or discomfort. Obviously if she had been, I'd have asked him to put her to sleep there and then.
