Hi All! I just came back from our local feed/supply store with my welded wire fence. I really wanted to get the 1x2 (6' tall) but it was REALLY expensive! So I got 2x4 instead (half the price!!)... How long should I wait until I let my babies out in that? Will they be able to squeeze through??? This is my first time building a run/coop... I didn't want to use "poultry net" aka chicken wire because I was afraid of dogs/raccoons ripping through it... I am still planning on installing a "skirt" of chicken wire at the base of the fence to prevent digging. Thanks!!! Kelly P.S. My peeps aren't even here yet!! They are being shipped on Monday!
