Haven't got the chickens yet, but am doing a lot of research. Any suggestions would be helpful. 1) Am considering building a coop surrounded by a small run. I have a huge pasture and will plant to let the birds freerange. Should I build a dustbath area nearby in the pasture instead of within the run? My thinking was that have a pasture dustbath area might entice them to want to go out into the pasture frequently. 2) I read somewhere that one fella waited until about 3:00 p.m. and then opened the run for the chickens to freerange, explaining that by dusk they all would return to the coop. Is that better than allowing them access to the pasture all day long? 3) Living in north central Texas, with few snowy days, but several freezing temps, is it necessary to install insulation and heat lamps in the coop? Folks up north do that, but do Texas chickens need that? Thanks for your advice. Much appreciated.
