Hi, I'm new to the forum and wanted to ask what size mesh would safely keep new chicks inside the run? I've a broody hen and she's now sitting on eight fertile eggs that I got for her as she's so desperate to hatch a brood. I was advised by the experienced breeder I got the eggs from to separate her and her chicks from the other two girls once the eggs hatch. I've a six by two meter run with a coop inside. I was going to partition off one third for mum and chicks until they can all rejoin the other two hens. I've got a nest box for mum and chicks and some fine gauge netting to divide run but it occurred to me, will the chicks be able to get through the 25mm chicken wire of the run? I don't want them to end up outside the run with mum unable to get them back inside. Should I run some of the fine gauge netting round the bottom of the run on the other three sides of the partitioned area? Any advice welcome!
