hey i have had my boys for about 2 months and when i got them they were being fed mr johnsons supreme guinea pig mix. its ok but because i have three pigs its really hard to know what each one is eating as they selective feed and they arent really getting a balanced diet from it. when we got them i bought a bag of it (which is massive and i only nearly finished the bad i bought when we got them). I have been trying to change them over onto the burgess excel nuggets but they dont seem to like them. i think they find them to big and hard so i have been breaking them up into small peices. its wierd though cos they seem to have on and off days - some days they dont eat any - only their origional food and other days there are only a few left. is this normal? also i think only one of them actually likes it.... but its really hard to tell who eats it and who doesnt. i only have about a weeks worth of their old food left so do you think i should buy another massive bag and just leave them on it for ages or do you have any tips on how to get them to like the food? should i wait until they eat most of the new bag if it get it and then try a different brand? what is your opinion? how do you get your guinea pigs to like a new food? i have been changing over gradually and at first they seemed to like it but now I'm not sure.... thanks in advance! x
