WELCOME TIM !
Chick Fest you say? Here's one of my hens with 31 offsets. I can't tell you the progression that this generation of chicks took...I ended up having to move them out of the bed to move to OR and thru hasty handling the chicks got separated from the hen. I would have left the chicks attached to the Mom as there was ample space for further growth and spread (well, maybe not on the right side of the family
)
Chick Fest in early March and then in early April:
Continuing onto late April and then to early June:
