About a month ago I posted about my momma Rouen who had just had her second set of hatchlings this summer & the first set were not happy with the ducklings. After some amazing advice from the BYC community I removed all 5 ducklings & kept them inside. This past Sunday they were 1 month old & I decided that was the right time to put them back into the duck house with the older ducks. I separated the pen with the ducklings in one area & the older ducks & drakes in the other area. 3 days later & all seems to be fine however after working outside over the holiday weekend on their newer & much bigger duck pond I noticed that momma & only momma was being aggressive towards them. She would lower her head to the ground & kinda charge towards them of course making them run away quacking for their poor little lives, lol! How long should I keep them separated? And will momma ever calm down?
