if so, how?
You can actually. The females are in the nest for the most part so you might not see them as much. But the males have black on there back, with the redish orange color on thier belly. the females are brownish with a lighter orange on the belly. There is also one called a juvenile, idk what they are, probably either one. But they have speckels on there belly along with white and orange.
i dont think you can...
its the same with rats and mice you just cant tell teh sex by looking at them.
visually theres no difference from what i understand.
i may be wrong :S
Mice and Rats are the easiest to tell at 3 weeks old a male mouses balls hang down, and a female has a pink opening. I breed mice would no. Have had rats they are the same way.
Matty, How many times do I have to ask you to stop playing with the mice...we have so many things to play with the computer...among other things...Leave the mice Alone! :P
Coloring is important, but if birds don't have dominate colors determining M or F. You have to get them sexed at a vet. I still am not confident what my African Grey is.
