I am certain one of my hatching eggs has two embryos in it. I saw two dark spots on day 7 but i didn't think it would make it this far into incubation. Lock down is on Wednesday. At last candling they were moving well and again I swear there are two heart beats ! Will it need help? Should I let nature take it's course? They have to be tiny being two of them in one space. I'd like to save them if there is the slightest chance but I've never helped a chick out. They are standard Salmon Faverolles not bantams i have been hatching so they shouldn't be micro chicks. Also i have one whose cell air looks like a saddle bag across the top. Again Chick seems fine. Will this one need extra care? Thank goodness i schedule hatching on weekends. Lol... Thanks for any advice. I never encountered these problems before.
