Hello, my pekin bantam Raven was absolutely fine yesterday however today she has been extremely lethargic, struggling to keep her eyes open and letting me pick her up when she normally runs off as out of my hens she's the only one who steers away from me. She appears to have some sort of limp and walking very slow or unbalanced. At first I thought this was down to heat exhaustion and tried making an ice pack to help however I have noticed her crop is massively swollen and feels as if its fully of jelly or fluid, there is no sign of redness however when compared to the other bantams they were fine. She can still run if need be and get around but she's not eating as much but she did drink ALOT of water before bed. Any suggestions as to whats wrong with her I'm extremely worried as through research it sounds fatal, please help x
