Hi all I am new here and just wanted to introduce myself. I accidentally got into breeding when I saw two lonely looking budgies in a sparse cage in a pet store. I bought them, brought them home, got them a more suitable birdcage and started feeding them a good diet. Well, they have been breeding ever since! The male is a green and yellow English budgie named Desi and the female is mostly white with a bit of blue and her name is Delilah. I am hoping to learn a lot about budgies and breeding here. I also have two male budgies, housed separately, that are from the first clutch. They were handled because mom and dad didn’t do a very good job the first time around but have gone on to become fabulous parents. My first question is that I am concerned about Delilah being overtaxed. It doesn’t seem to matter what I do she just keeps producing one clutch after the other. I have tried removing the nest but she becomes frantic emptying every food dish etc trying to make a nest and will still lay eggs. I have tried separating mom and dad but they both become distraught when they can’t be together. How do I get her to take a break? Can anyone tell me the proper terminology for their colours?
