Hi. I'm new here. and new to raising chickens. 6 wks ago purchased 2 bantys and 2 reds. both young layers. Am letting them free most of the day now. The more comfortable they get, the more they tear up the mulch in the few landscaped areas we have. The wife aint happy! I ve trained my border collie to run 'em off, but he's with me at work all day. She doesn't want to fence in the landscaping. Is there something I can put down to discourage them? pepper? something like that? thanks.
