So the simple way of asking: **** 1) Is the larger holed chicken wire safe for preventing hatched babies from going through? Or will they have no desire to go away from mom? (Or by the time they want to, they can't fit?) Our chicken pen is roughly 40x40 ft or bigger. it is field fencing with chickenwire over it. It is the larger hole chicken wire. I am really hoping that is a large enough pen that the babies won't try to stray from mom enough to go through holes, at least until they are too big to fit? 2) Can she brood out the babies in her own little house, but have it be not separated from the flock fence-wise (so within the fencing of that 40ish x 40ish foot pen)? Thanks!
