Hello, New to the site and not sure yet how it works. We lost our rooster 2 wks. ago, the hen that was closest to him is now mounting our younger hens this started 2 days ago. The (Sussex) older hens (2) are 1 yr. 3 mos. the younger hens (4) are 7 mos. and are a road island red/ buff orpington mix. One of the reds has laid one egg since March and the other (the one that is trying to replace our rooster) has recently stopped. Is this normal chicken behavior? The 2 reds are very hateful and would rather spend their time beating up on the other 4. Please help. Thank you in advance Shirley.
