Decapitated chicks inside cage?

[Melissa67137]

Came home 2 more injured, no way any cat could’ve gotten in there or reached through, went ahead and moved them inside. they all have some sort of scratch or cut on their neck, is it mom ?? View attachment 3466785

This is exactly how my one chick looked when the old hen about pecked her to death......seperated chicks from hen, or make small escape hiding places for the chicks to get away from the old hen......on the wounded chicks use vetricyn spray multiple times a day for several days and my chick healed up great.
