Muscovy duck advice

[mute]

I have a broody Muscovy duck but also have Muscovy eggs in incubator. She has only been broody a couple of days and my eggs are due to hatch in about 3 days. my plan is to put eggs under her and let her hatch them. Will this be too soon for her considering shes not long been broody. I've heard you can't put already hatched ducklings under them as during hatching period is an important bonding time. Would like duck to rear young as they are great mums but don't want to risk eggs/ducklings by mucking it up.
