Hi folks. Had a great hatch today. Our second round in one week. Almost all doing great, but one little chick emerged with a crusted over hiney, and it looks all swollen and it's got a bit of shell stuck to it. Is that what's called pasty butt? I thought that was a condition that emerged after theyve been in the world a few days. What else could it be? What can I do? Thanks for your help.
