I have a partridge Brahma hen about 18 months old. She presented with a hard crop about golf ball size. No other problems and laying as usual. In the morning she still had the hard crop. It was a bit softer but not empty. I separated her two days and fed only water with a bit of epson salt and maas ( type of unflavoured yogurt) I massaged her crop and it went down and emptied after 2 days. Hoped that the problem was over and let her be with the other chickens. After a few days I noticed that we are back at square one. She had again a hard crop in the morning. I isolated her again and only fed maas and water with a bit of ACV. I also gave her 2.5 ml of olive oil. Two days later the crop is softer but not fixed. This is not sour crop as there is no foul smell.
This morning I took her to the vet. He cut open the crop and emptied it. He also took an x-ray. Normal crop contents and normal lining of the crop. Only thing I am not sure about is the amount of grit in her gizzard. I think that there is a lot of grit in her gizzard- more that what is "normal"?
My question: 1. Has anybody any idea of how much grit is usually in the gizzard?
2. Should I do anything more and if yes what?

X-ray of "Spikkels" - she laid that egg as soon as we got home
The next picture is of the contents of her crop

This is the one story. I am going to start another thread for the other hen's story as it seems as if I have two hens with two different crop problems at the same time
