I have one that is small mouse size that is eating and getting around. I just noticed him two weeks ago and started giving him apple sauce consistency rat block watered down. His siblings are large weanling size. Because this little guy is eating on its own do you still think its cruel to keep him around? There is obviously something wrong with him, but he comes running to the front of the bin every time I open it. Kinda look forward to seeing him every day.

Think he is suffering and I should cull?
