Its day 10 my eggs have been in incubation for and i candled them tonight. I came across one of my eggs and noticed two dark spots developing in the egg both with movement. It may be me just being silly but i thought their might be twin chicks inside as i have heard of this before. Do you think there is possibly two chicks inside or is it one? P.s i know its a bit porous the shell but its developing so well i kept it in the incubator Here it is: can you see the two blobs?
