That's normal for their first eggs and they are usually smaller than they will be too. Congrats on the new layer.
Its def one of the EE's from you. Naturally she willbuse the same box as the other 2 that are lating so will take some time tonfigure which, but i knew someone was close. Have a good feeling ti was zoey that laid...but we will see!
And yes it should get bigger. First egg was comprableto the yokie eggs, so all should be going well! Now for the egg barrage!

But I am not getting them all at one time. The baby goat won't be ready for a few more months. It's only two weeks old right now. The cow is a 2 month wait. The turkeys, those are waiting until we get the pens fully finished. She hatches year round pretty much. But I know where I am getting them. She is also the one that has the bull. He won't be mine but will come visit her on occasion. I swear I haven't added anything but a dog (dumped on the property we think) to my collection of critters.
