Ok well this is more to find out what the heck went wrong and if maybe I should never take the chance of breeding the chicks daddy again. Ok 8 week old, maran mix. Started out the same size as everyone else. At the time of death it was only slightly larger than it was at hatching and its hatch mates were at least 3 times or more its size. I posted several times and with the information I got I decided as long as it was eating and drinking it was small but fine. Was very active, never sick. Yesterday it was acting a bit off. This morning it was on its side dying. It had a HUGE black knot below its vent that I know was not there before. I hold the chick alot hoping to make it a pet since its so small and the lump was not there until yesterday or at least not where I could feel it. Could its not growing be linked to this lump. Possibly genetic issues or hatching issue? If I think its genetic I will probably elect not to hatch my own again to avoid it. Its been a long 8 weeks and a very sad ending.
