Yesterday we had a wild tom turkey and 4 hens wander through our yard. Do I have to worry about free ranging our girls after that? They walked near the coop/run and lingered in the yard. I was planning on worming the girls with something like Valbazen before winter. Do you think it's necessary? They are all 21 weeks old. I have a RIR, Buff Orp, Black Australorp, and an EE. All but the EE are laying. I just want to be sure my girls are safe after this visit. Thank you!
