how do i introduce a mom to her own chicks? she has chicken eggs under her now which i placed in with her when i put the duck eggs into the incubator for the last week or so. she's in a small chicken house and very aggressive when i go in to change water or give pellets. when she comes out she hunches down and charges all over the place scaring the two other poor hens. but not the drake lol we are four days from 28 days and two hatched from the incubator already, night before last and this am. 12 hours in i tried to place the duckling in with her, but she is so aggressive towards me i think is why she took a few swipes at the chick a couple of times. so removed it. now it has a friend. i have four eggs remaining in the incubator and mom is sitting on several shicken eggs. at this point i'm very hesitant to put the duck eggs back in with her... i can' supervise them without having my head in the coop. if i have say four ducks hatched in the incubator, the oldest being four days old to newborn, do i try to put them in with her? i would have to move her into a 4X8 coop though so she and they have lots of room for food and water and wandering chicks. they will be going in with her and then they'll all join a drake and two hens... what to do???
