I’ve done both of those things she does take some paper shreds and then uses it but then she changes her mind and throw everything out this is her first clutch that she’s raising (her very first clutch she abandoned the babies) with a partner (not a very good one at that) if I bother her and move the babies to much (like I did last time) she will abandon or kill them like last time I’ve checked the babies and the legs are completely fine (as in not splayed) and so is the rest of their body and there growing at a normal rateDon't leave it. Do something about it. It is an easy fix.
Either tip in some shavings when you are inspecting the chicks next, or give the hen some paper and let her shred it and make the nest herself.
