hi all I'm after some more advice please. i had an issue with my pigs and have posted on here before cut along story short ive had my 2 males together a 2year old and 5month old (i am new to this) anyway all seemed ok no bite mark etc ( ive been stupidily looking at his ears he has a long coat so nothing really noticable and they seemed to be getting on ok. after a week or so ralph was looking depressed and we thought he was being bullied still no sign of fighting anyway we decided to split them it was only then that i noticed poor ralphs bite marks on his lower back, since splitting them ive brought ralph back inside, and hes also been to the vet and has been given antibiotics hes still eating and drinking but seems really depressed and unhappy like sleeping out in the open of his cage or am i confusing this with comfortableness of him being back where he belongs? its making me worry and i dont know if this is unnessasary or not? or if I'm making it an issue now? he only seems to squeek is when we go to bed he used to for food at dinnertime his appitite is the same and hes eating his greens like their going out of fashion so I'm not too worried with his eating or drinking i know ive messed him around i really dont need to be told i feel so bad for not being more attentitve hes a member of my family and feel awfull ive attempted to pair him with a friend for it to turn sour hes the most laid back chap and i wish i knew if hes feeling depressed or whether its me being paranoid :...:...:...( my other boy norman is fine hes been checked over by the vet hes my little bully
