That can be one of the causes, too warm can cause other problems too.I got 5 new babies today. 2 Barred Plymouth Rocks, 2 Silver Laced Wyandottes and a Silkie Bantam that my boyfriend wanted. lol I hand picked the 4. I got the ones that were running around eating and drinking. I didn't pick the Silkie out. The manager at TSC got her for us while we were picking out some other items. The Silkie is to replace the one little Isa Brown that didn't make it.
They are so little! Omgosh, I don't remember my 1st batch being so little.... They are 2 1/2 weeks old. I really hope they do ok. I checked all their bottoms... so far so good. (Is it true pasty bottom is from a brooder that's too warm??)
I have them all on Save A Chick electrolytes and probiotics. They are all eating and drinking and cuddling under their light. The Silkie is a little older I'd say... she's just a little bit bigger than the others.
