I have Golden Comets, Raised them since Easter, I am feeding them layer pellets mixed with grit. I have had 2 die laying eggs in the last 3 days, I do not know if it was their first time laying or not but it seems that way. It appears that the eggs are too big for them to have without going into details of what their backsides look like. The chickens appear big enough like I said I have had them since Easter as chicks. Please Help..
