Just an update on my recent hatch (1 week old today). I lost one of the babies within 24 hours, seemed healthy then went down hill fast. At three days old, another started getting sick. I noticed bloody poo, so started corid for cocci. Baby did not make it through the night, went from a healthy, normal chick to dead in about six hours. The next day another started showing similar symptoms, not wanting to eat, a little lethargic. I did more research, and found out cocci has a five day incubation period, so couldn't be what was killing my chicks. After talking to some wonderful people here on BYC, I determined that it must be a bacterial yolk sac infection, very deadly and hard to treat. Of course, this was in the evening and feed stores were closed. I had antibiotics on hand (for a root canal that I just had), and after some research found out that they could be used for birds. (cephalexin) I made a very diluted drench with water and the capsule (baby was only 2 ozs) and was successfully able to save the third chicks life. I say all of this only to help anyone else out who may be losing chicks. I have only hatched one other time, and all the chicks were healthy and hardy. Apparently this can happen in any situation, dirty eggs, clean eggs, incubator, broody, etc. The next time I hatch any eggs, I will have baytril on hand to add to the water in case anyone shows any symptoms. I didn't know this before, and it cost me the lives of two of my chicks. I am thankful that with some assistance from BYC members I was able to save the other chick, but of course sad that I lost the other two babies. It is totally my fault that I didn't know about this, and I don't want to go into another hatch without all the info needed. The three left are doing great, super cute (of course) and running around with mom.
