My 8-10 mth old d'uccle has stopped laying and out of my 3 recently purchased 1 1/2 yr olds only 1 has layed 2 eggs in about 3wks. Are d'uccles just poor layers in general? I feed layer pellet and oyster shell and allow them to free range till bed time. I put the apple cider vinegar in their water and dusted them and their home with diatomaceous earth. I've even tried the dried crushed jalapenos....the two eggs I got were in the two consecutive days after this but nothing since. My easter egger lives right along with them and faithfully delivers an egg a day like clockwork.
