Ok, So I've been planning on putting a couple chicken tractors outside for my silkies. However, I'm hearing some concerns from people... Do you think they'd be ok for silkies? They roost on the ground, that's my only concerns. I think the concern is that raccoons might get them. They are well made with chicken wire. Has anyone had any issues with them? I just need reassurance and advice on keeping the critters away from my silkies!
