i have a yellow/green clerwing hen that is in my avairy at the moment(not breeding her at the moment) and she has an almost black cere. is this normal or is there something wrong with her? if there is, what treatment is needed? thanks

Photos would help greatly if possible.

I have never seen a black cere on an adult bird, only on some chicks. A really dark brown cere on a hen indicates she is on the way out of breeding condition, so it may be that.

thanks! will take some photos and post them tomorrow as im about to go to a wedding. Without looking at my records im pretty sure she is a 08 bird.

will post some photos soon.thanks again!

Yes chocolate brown is normal ~ black .... mmmm, not so good. Pictures required!
