Sorry to hear about Joycie.
I have a couple of SLW,a d they were late to start their molts,and are taking a long time. One is a real character, and has wormed her way into our hearts. So when she decided to help herself to some of the food in the bucket I fill the bowls from, I did not complain, and now every couple of days she walks back to the basement with me for a little extra feed. I feed Flock Raiser which is 20 per cent protein, and she is regaining her feathers a bit before her " sister". Being smaller, it is a bit hard for the SLW to compete at the food bowls, and Eunice refuses to adopt the ill tempered attitude that Flavia uses so effectively.
Perhaps some special rations would help your girl?
