I check for eggs every morning when they are due. On occasion the females lay directly on the tub. They come off easily, I just sloooowwwly peel them off. I never had a problem but I guess if they sat for a while you may have to be more careful.
I'll be checking daily also. I just have to work and having my wife pull eggs has the potential to be a disaster. The eggs I got last year came off the tub fine but I was curious what you all have experienced.
