Stud is definately a female... she´s pearl and cinnamon.. sex-linked traits for females... and a very pretty one... just let the owners know she´s on eggs and she´ll need to increase her calcium so she won´t deplet in vane (all eggs are unfertile, no male=no babies )

Bob looks like a green cheek conure.. but I´m nor really sure... the canaries are lovely!! love the orange ones (reds)... and Bonnie is not a budgie... looks like a lovebird, agaporni or something but not a budgie

Cowboy is very cute (and looks more like Aussie or BC than cattledog ).. and Jumbo!!.. Oh my.. how tiny he is... I love the name even more LOL...
