Canaries For Sale in New Lisbon, Wisconsin

Hi, I have 4 Canaries for Sale.
One is all yellow with a green spot on the back of the head and the other one is all yellow with a green spot on the back of the head and one green spot of the wing. I have seen both of them sing now, so I believe both are males.These two are siblings.
One is green and yellow. I have not seen this one sing yet, so I believe this one is a female. Not related to the other green and yellow ones.
One is a crested multi color. I am selling this one as unsexed right now with it being so young. Not related to the others as well.
If you have any questions please feel free to let me know. Thanks and have a wonderful day.
Asking $50 each or if you buy more than one you can get them for $45 each.
