Ok so a lash egg still in the oviduct. My girls have had loads of these. Sometimes they lay them, sometimes they can break down and get reabsorbed into their system over time. Just to let you know with the type of Marek's that causes paralysis, in some cases the paralysis passes after 24-48 hrs and the hen is fine again. But she will have it in her system. Are they all vaccinated?The vet felt an under-developed egg, we think Marek's and likely will get her euathanized Monday.![]()
