Hello I am new to the forum and concerned about my chicks. Recently we had put about 14 eggs under a wonderful Wyandotte brooder. The 2 that were to hatch yesterday were dead inside. They appeared to have died at about 12days, I am so concerned about the rest of the chicks and am not sure what to do or why they would have died. We do not have an incubator, so we brought our girl in the house with the eggs so she and the babies could be safe when/if they hatch. Now I am not sure what to do, when candled we can see the air sac and a black mass, but that is what we saw with the last 2 that were dead. Should we hear something or feeling something or see something if they are alive? Help please we don't want to lose all the babies and if they are gone already then what did we do wrong? Thank so much for any help.
