Hi, we have three lovely budgies. The green budgie is Brenda, the white budgie is Patricia and the blue budgie is Bruce. We are fairly certain that Bruce is male but the green and white we were unsure of- we think female but not sure
Bruce and Brenda look like Hens, Patricia is possibly a male.
Clearer photos would help to clarify with all though.
That's the way I was thinking, as well, and also regarding the photos. I'll go out on a limb and say Brenda - hen; Patricia - male; Bruce - possible hen. Closer photos and clearer ... head shots are best.
We are not Vets, Avian or otherwise. If you have any serious doubts about your budgies' health an appointment with an Avian vet should always be your first point of call.
