Big part of it is just that this your second year.I can't explain it very well, but there's just a different feeling with these chicks than last year's brood. It's a contentment that comes from just being around them. There's the belief that even though they had such an unnatural introduction to the world, starting life in a brightly lit hatchery with thousands of others; even though they were dumped in boxes and spent days traveling; and even though they had never laid eyes on a Mama Hen, the rest of their time as chicks was as natural as it could possibly be. This year I raised chickens instead of little prima-donnas and I actually feel more bonded to them than I did to the ones I raised by the book. Am I crazy?
It's easier cause you've been thru all the 'firsts' that you didn't know about, and rectified all the 'myths', just like with the second child.
The chicken learning curve is very steep!
Part is definitely the heating pad vs a light. Chicks are much calmer without a light on them 24/7, no doubt about it.
