Egg Hatching 101: Day 11 Blanks











We are on day 11 and now is a good time to talk about blanks.

Blank eggs... what are they? These eggs aren't developing, were probably never fertilized, and need to be removed from the incubator. If you are candling eggs that you can see light through and you aren't seeing any development, it's a good time to think about removing them. Eggs that are too dark to candle properly (such as Marans eggs that are dark chocolate brown), I typically leave in and give the benefit of the doubt.

The above photo shows a good example of a blank egg on day 11. At this point, you should have a noticeable dark blob that probably reacts to the light by moving around.




Today, we're on Day 11:




  • Padding on feet is starting to form

  • Feathers are beginning to form on the back and tail

  • Beak continues to harden

  • Comb continues to develope

  • Embryo starts drawing calcium from eggshell to support growing bones.

Team Greta

Friday, February 9th started off as a normal day in the barn, but as I was doing chores and feeding the horses and goats, I quickly suspected that Greta, one of our La Mancha goats, was showing early signs of labor. It was her due day, so I wasn't surprised. I removed her from the herd and placed her into one of the three kidding stalls in our barn so that she could have some peace and quiet. Four hours later at 10:46am, she delivered two beautiful big twin boys. As per her normal (this is her third year with babies), she was quite proud of herself and insisted on showing them off to me nonstop. The twins were up and wobbling around in no time and Greta was a busy mom fussing over them. Saturday morning was uneventful and Greta and her twins were comfortable in their kidding stall, but by early afternoon, something wasn't right. Greta wasn't finishing her meals and she just seemed tired. I took her temperature at 3pm and it was normal -- 101.9 -- even though she

Snow Update: She's A Rock Star Circus Pony

Our original plan (with our vet) was to wait until this fall to test Snow for Cushing's Disease because the test would be more accurate. However, despite the diet change, supplements, restricted pasture access and constant monitoring, Snow has continued to have Cushing-type symptom issues, including increased hoof tenderness. (If you're jumping in now and don't know the back story, we found our 30+ yr old miniature horse Snow having a seizure in her stall in July. You can read about it here.) We have been consulting constantly with our vet through the whole ordeal and we made the joint decision that we should go ahead and test her as soon as possible as well as x-ray her hooves to look for the beginnings of any rotation. Of course we have Hurricane Hermine moving in on us, but Dr. White was determined to get this done sooner rather than later so we can start treating her with the medication she needs if she is positive.
