[Spitman]

my Broody hen hatched 6 chicks about 1 1/2 weeks old doing great seem fine but there crops look a little bit swollen to me . i had a swollen crop problem about 3 months ago with some adult birds but treated them , and they got better . But it looks like the little ones are getting lopsided and a little swollen in there crops any idea's help. I did not feed them special feed or anything they have been eating what the adult birds eat. advice please.

Can you feel of them? Are they soft? Hard? Grainy feeling? I notice a chicks crop will stay more full than normal.
