The only person I know of who could supply them is under the quarantine zone, and her packages do travel through the qz during transit. Out of biosecurity, I won't recommend.Even if its a mixture of them, I wouldnt mind.
I dont show any of my birds, so it wouldnt matter. Either breeding and/or pet quality
I have 8 d'Uccle eggs currently, plus lots of Japanese/Serama project eggs but full disclosure I'm not sure how old each individual egg is.
