I had them in a little giant incubator (again, long story short I found a huge clutch of eggs the mom was pecking to death as they hatched so the whole incubator set up was rushed/last minute and so far I have 12 healthy chicks and this guy) and whatever the fluid was, there was enough to turn the water in a 1 inch wide and maybe 5 inch long water trough green/brown and I could see i guess what could be poop in it. It wasn't just fluid I mean, there was something else in it. Anyway, The chick started hatching yesterday morning and didn't come out of his egg until 6 or 7 last night. I could see he did have some yolk still but after about an hour all I could see was that red bubble. Then at about 11 maybe he released that fluid. I would like to avoid tying off the sac if possible, I am such an amateur in this department I would like to at least attempt to let it absorb on it's own but again, I am an amateur so please advise me of you and your friends thoughts on this. I can also post more pics if need be. Any help is so appreciated though! Again, I would really like to save him. Thank you so much.
