Just came back after a few days away, during which my neighbour looked after the chickens.
I have 5 x 8 week old Hubbards. However I have noticed that 2 of them have what looks like a large ballon on the chest. It starts at the base of the neck and fills my hand. It feels completly empty and there is no smell from the crop so I dont believe it is sour crop.
They are free ranging albeit very lazy. I have not provided them with perches so that there is no malformation of the breast. They are not in an pain when squeezed, Any ideas?
