If they are just starting up laying they can lay soft shell eggs and this might be the remains of one. Make sure they are getting plenty of calcium in their diet they need it to make good strong egg shells. If your feeding layer you might want to put out oyster shell for them some just need more calcium than they get from diet and they will only eat the oyster shell as needed. Fresh chopped Kale is another good way to give them calcium.
I don't think you are suppose to wash the eggs you are going to let her sit. It washes the protective coating that keeps out bacteria so you might want to bring them in and eat them. Usually when they first lay eggs are smaller they get larger down the line.
Especially first time broody's I only give them 3-4 eggs to sit. Once they commit to sitting you could take all of the away and she would continue to sit they get so dedicated. But I'd let her have at least 3-4 that way if 1 or 2 didn't make it there would still be 2 and it is much better to have 2 or 3 grow up together. You can give her as many as you want I like for mine to have small clutches too so I don't get over run. So what do you have 1 drake to 2 females?
Perfect.
would two females lay in the same nest though? I wouldn't of thought they would.
