My Banny momma hatched eight babies on 10/25. They were doing great, until I checked on them today. I had one dead chick, and three others that look like they will die by the end of the night. They have been eating, but when I felt their little chest it was like they had no food in them at all. Their little chest bone is sticking out. My Banny is a new momma so I don't know if that is the problem or not. They are on the proper food, but it's not medicated. I haven't treated them for worms yet, but will get some first thing tomorrow. I just don't know what to do. Is this normal? What can I do to help these babies? This is my first set of babies, and my heart is just breaking. I have the momma and the babies in the house because the weather has been cold then hot, then cold again. This have been an influence. Please any advice is greatly appreciated.
