i have a consistently broody silkie and once again hunkered down. i am in the midst of building a new broody pen....but with rain etc i am thinking a solid week away from done. she has been really seriously sitting for 4 days as of today. how long can she sit before i give her eggs ...wanting opinions! i had one broody for4 weeks and could not break her, then gave her eggs and she was DEF over it by the end...she hung in and hatched most...but as soon as the first hatched she gave it up...i saved them...but rather not put a hen thru that..it is a long time! SO, safely how long to y'all think????
