Growth on 2 wk old chick

[kmarkin]

I just found this on one of our chicks today, it seems to be growing at a rapid pace. I don't see any vent blockages and chick seems to feel well otherwise. Anyone know what this could be and how we can treat it? We've raised chicks before but this is our first time to hatch our own.

I would ask a vet or call metzer farms in California they are happy to answer any questions or concerns

Hi and wow!
remove it from the other chicks. if it going to burst, you don't want the other chicks trying to eat the excrement from whatever it is. I would take this to the emergency and illness list. Someone there may have seen this before. Make sure and wash between handling this chick and the others.
