Hello, I have a RIR 6month old who is on antibiotics for respiratory disease and I need to try and fatten her up as she is quite underweight. Does anyone have any healthy nutritious suggestions to help? She's not a fan of the layer pellets, and not overly interested in the lettuce, apple or capsicum, but loving diced up boiled egg. She will eat the seed mix but the vet said to take that away if I can because it doesn't have much nutritional value. any suggestions? Thanks!
