So I've got one little chick that has had pasty butt issues for a week, a hatched chick not a shipped one. I kept cleaning off the bum twice a day with a warm washrag and then used a q-tip to apply some olive oil. Two others had issues for a couple of days, but stopped getting pasty bums quickly. I am concerned because today I can tell the little one is starting to get dehydrated. Its little feets and legs are definitely starting to look taunt. So after the most recent bum cleaning session, I had the little one drink some lukewarm water by dipping its beak in the water. I know it has been drinking, but either not enough OR constant diarrhea is taking its toll. The little one won't touch the yogurt I've offered, either by leaving it in the brooder and putting chick crumbles on top to make it more appealing, or hand feeding. I've tried smearing a bit on the side of the beak so it'll eat some, but no luck. The chick still has the strength to complain when I clean off its bum and then run back underneath the ecoglow brooder afterward before resuming normal chick activities of running around the brooder. What else could I do to help out the little one? It is a blue purebred araucana (not tufted, but still) and I don't want to lose it.
