Chickens with Sour Crop

[Hiimscott]

Hi guys, I've just found 3 of my 20 week old pullets with what seems like Sour Crop, I have withheld food. I read somewhere that a crop should have a ph of 5.5, I own a Kangen Water Machine. I'm wondering if I used a Ph of 5.5 for their drinking water would this help?

Apart from the watery balloon like crop, they seem fine. Not sure why 3 have come down with it at once.

I haven't changed their feed, they are fed Laucke Mills Pullet grower
