My 6 white leghorns have been laying for several months now but my 3 domoniqus are just now getting old enough to lay. My 3 nests are at one end of the coop and my leghorns always use the nests. But...yesterday while cleaning out shavings I found 3 soft shell eggs on the opposite far end of the coop which also happens to be where the 3 domoniques roost AWAY from the leghorns. 2 softys were tiny eggs and the other looked like a large. All 3 were in the same spot. Could these be early first eggs from the doms? Could the leghorns not want to let them nest in THEIR boxes? Is this activity common? I ALWAYS have shell and grit out for all the birds. Leghorn eggs are ALWAYS good and strong shelled. What is happening here?
