So, I have 2 runner ducks that I think are girls-they are a speckled white and brown not very pretty, 2 pekin ducks that I thought were boys but they quack alot and now Im thinking they are girls and a grey duck that I have no idea on. I have 8 hens (1RIR, 1brown leghorn, 6BR) and a roo. They are all between 4-5months old. I just started getting eggs. The 1st day was a white egg the size of a large chicken egg, then the next day 4 white eggs the same size then a few days went by and today I found a huge egg, it cant fit in the egg carton. Help, I dont know who is laying. What ducks, what chickens argh. I know pekin duck eggs are monsterous, what about runner ducks? Do Brown leghorns lay white or brown eggs? Is there a way that I can tell who is laying?
