Lovebird identification

[Barbara Hohmann]

Please help, I am trying to identify which type of Lovebirds I currently have. I thought I knew but lately people have been telling me that my birds are hybrid and cannot be bred. They have all had babies but I am wondering if the babies will be able to breed

First two are peach faced lovebirds (Roseicollis).

The rest are Personatus or Personatus hybrids. Are any of those offspring?

Offspring from a Roseicollis and a Personatus pair will be infertile.
