Congrats on the eggs!! Yeah, don't worry, roosters do that to try and win over hens. My Barred Rock does it as does my silkie rooster. They will get into a nest, call the hens to come and see it, set it up all nice looking, and then when a hen comes they try and say "well, I've made a nice nest, might as well raise my babies in it!" It does look really funny though and for a while I thought my silkie rooster was going broody!
