Female acting weird?

Soo I'm breeding 4 normal girls and this is my first time breeding, all my girls are eating fine except my first girl to lock. The first girl didn't eat on Nov 11th and then continued on to have her first lock on Nov 20th, she then shed on Dec 6th and ever since she has not eaten. Do you guys have any idea why she would be acting soo weird but all my other girls are feeding like cows right now?

Some go off feeding while theyre breeding. Im pretty sure its not abnormal. The only cause for alarm would be if she starts losing weight.

This is normal for balls, specially breeders, to go off feed. This has been stated in many breeding posts.
