Will my new Muscovy ducks Breed?

[Dmitry]

Hi i just got 4 new muscovy ducks 1 drake and 3 hens and they are very scared of me and they have plenty of space and a little bit of spaces to lay eggs and hide so i was wondering if they will be breeding and laying eggs even tho knowing i come in the cage that is 30' long and 15' wide to collect chicken eggs and check on my rabbits water and food.. they have unlimited amount of water and food as i fill it up everyday. so please anyone know when they will be ready? when will they be tame and used to me as they have not been around people alot.?
