New 1yr old Broad breasted hens

[Coops Dad]

Unfortunately toms that are human imprinted can be very dangerous and violent.

I know it but some people won't learn without going through an "Old Yeller" moment. I married one and sired another.

How can I undo what the last owner did in imprinting on them?
I just ignored her today and put her with my Tom and the older female for a few hours.

You really can't undo imprinting. Your tom should eventually get to mate with her if you leave them alone.
