If she's a fairly calm bird and is used to being handled, she may fuss but hopefully get over it quick.There is no vein there. It's thin enough and pale enough to see through. I may try to clip it tomorrow. I don't want to stress her out but I think it looks like something I could do without moving her if she'll let me.
Might be better to do it after dark if you've got a helper.... or a good headlight.
