I am wanting to expand my run to give my chickens some more room. Their current run is very safe (chain link 10'x30', 6ft high, hardware cloth on bottom half that runs 2ft under the pen & is attached to the ground with landscape staples, & it is covered. I have an extra door to the back of the run & was wanting to fence in some additional space for them. I wanted to know if I could get by with using T posts & poultry wire for that run. I would need about 120-150' of wire. I wasn't planning on covering it. Basically this additional run would just be so they would have a little more room. I would still have the option to shut them in the 10x30 run & not let them in the addition. They would be out there if we were home & outside working. I can't really let them free range because we have a 30 acre corn field on the other side of their coop/run & I'm afraid they would get lost out there or get killed somehow. Anyway, I just don't know if I'm on the right track with this or if I need a sturdier fence (if so, what kind?) & how tall it should be etc... I would sure appreciate any ideas you may have! Also, if it matters the coop/run is close to the house & barn so I don't think I've got alot to worry about as far as predators during the day. They are locked up in the coop every night & locks are on the doors to the run also. Just in case that makes a difference.
