Just the other day I found that my Khaki Campbell(I think) started laying again, but before I could collect them my dad accidentally stepped on all four. Then we had to catch the two East Indies that were being sold, and that stressed all the ducks out, so she quit laying for a couple of days. Now I found one again today, but I want to know how to find out if it's fertile or not. I have a Cayuga drake that is always with my two girls, but I know that doesn't guarantee fertile eggs from the start. Also, this egg was sitting out most of the day, and we had temperatures dip below freezing, will it still be viable for incubation, or should we just keep it for eating? Also, I think I've asked this before, but do you guys think an injured hen will lay? I only have one Cayuga hen, and her leg was broken as a duckling. It began healing too quickly for our vet to set it, so she limps, but is otherwise healthy. Will this stress her body to the point where she won't lay? She's almost a year old(so this will be her first breeding year), and to date I don't think she has laid once, and it's my understanding that they're supposed to lay at around six months. I'm pretty sure the one laying is my Khaki Campbell.
