We've chatted a bit in another thread about this already but I'm responding here so I'll get notifications. As I mentioned before, it's really just a wait and see situation. Sorry I can't say anything else more certain. You will almost certainly know within a few days. It tends to be about 50/50 for chicks that don't finish absorbing the yolk. whatever isn't absorbed will dry up and fall off with time. Just be careful to keep a clean brooder and if at all possible to get chlorhexidine I really feel like it's the best product for these situations. Just dabbing it on the navel area daily will help to prevent bacterial infection like the antibacterial ointment but it isn't sticky like the ointment is and will allow it to dry more readily. Fingers crossed the little one pulls through for you.
