I have 4 females and one drake that have all been together for just over a year, never had any problems with them they all got along great. A couple weeks ago I added 4 more ducklings (not 100% sure the sexes yet I know one is a female) they don’t share a house yet but they all free range outside in the last couple days I’ve noticed my older ducks are starting to fight and push eachother around last night my girls where chasing eachother, one of them chased the drake and then the drake chased her back. Again they’ve never done this before. Does anyone know what is going on and how to stop them? I don’t think it has anything to do with the younger ones I just added because I’ve done it before with no problems.
