I noticed last night one of my 14 chicks has a swollen red vent, looking like a little red button. From reading on this web site, I cleaned her with mineral oil(her vent was not blocked), applied cortisone cream and fed her 1/2 teaspoon of coconut oil. I also resumed putting quick chick in their water and increased the temp in the brooder back to 90 degrees. The other chicks are not paying much attention to her as far as pecking. I also saw her poop after I gave her the coconut oil, a soft consistency manure. Today she is keeping to herself and looks like she's not feeling well. The swelling looks a bit better, but not gone. I'm wondering what else I should do? I did clean her again with the mineral oil and apply the cortisone again. Should I give her more coconut oil? Thoughts?
