Hey brainstrust!
I have a broody light sussex bantam whos doing such a good job with her eggs however iv been watching and monitoring a wyandotte hen whos half acting broody half acting like the light sussex is her baby!?
Iv given the wyandotte her own eggs to sit on but she doesnt stay on em she would rather sit on top of the light sussex to the point my poor light sussex has to move away from her eggs n usually she'll pop onto the eggs iv put for the wyandotte but then the wyandotte will move to sit back on the light sussex
Its making for inconsistent incubation for the fertile eggs and id like to understand whats going on with my wyandotte if anyone has answers or an idea please
All my light sussex wants to do is to sit on her eggs and look after em but all of a sudden the wyandottes decided the light sussex is where she wants to sit on
Please help

Yea il separate her but do you know why she would be acting this way tho? Is she confused? Does she just want to help the bantam? Or is this a domainance thing?
