This little chap or chapess here is the same age as his/her siblings, just under twelve weeks
So why so small? Well, when she (we think of it as a she although we don’t actually know) was a few weeks old, she developed a limp which took a while to go. Growth was slowed at that point presumably as energies were put into healing, rather than growing, but since then her growth rate has continued to remain very slow indeed, almost to the point of non existence. Everything else seems fine so quite how big she will get or whether she will survive or not, is very much up in the air.
And of course, what will become of her if she does survive???
