If i were you i would let them free range in the fenced area. Besides not all chickens are fans of tomatoes! Mine aren't at least. Give them some more time if you so not see serious injuries... And observe them more, that helps solve the problem a lot!
40 waxing and waning free-range birds.
I truly love animals, both male and female, large and small, regardless of how important humans may shallowly deem them.
Well, No idea how much I should worry the little buggers are pecking at each other as well as the big girls getting them once in a while. Caught one of the little polishes chasing another little polish!
