A RIR chick hatched yesterday and everything seemed great. It's been doing everything it should. But then I noticed today that it was walking with its legs sticking out really far to the sides. So I checked it out and saw that there was a "bubble" sort of thing attached to the navel. I thought it was just part of the yolk sac so I was gonna wash it off but it's like attached. I'm not sure what to do. The chick punctured it with its toe and now its oozing blood and yolk. The chick isn't doing so good anymore. Any help is appreciated!! it's pooping ok but hasn't eaten.
