My 18 month old Arucana, Flossie, went through her molt and started laying again, but hasn't laid an egg in over a week. She seems just fine, eating, pooping, scratching. I have 14 hens and a rooster of different breeds and they all seem quite healthy and happy. They free range most of the day with access to the food and water all the time. My husband said he saw Flossie in one of the nesting boxes earlier today. When I went out I found a brown egg and a shell- less egg. Flossie lays blue eggs. The shell-less one might have been hers. Is this a normal occurrence, to be laying and then to stop? Is there something I should be watching out for with her?
