I'm new to this chicken thing-only a few weeks into it. We built a chicken tractor with a 4x3 house and a 4x9 run, 3 feet tall. We have three white leghorn/RIR mixes who are almost 22 weeks. They are flighty and nervous but seem happy otherwise. They aren't laying yet, which is frustrating but I guess it's like a watched pot. I posted a couple questions (thanks for the help on those) and searched extensively for my others without luck. This may be more appropriate in the behaviors/egg laying or feeding forum but I'll try here: -We put straw in the house and nesting box but they scratch it out into the run. I put a 2x2 in front of the nesting box to try to prevent them from emptying it which helps a little. Do I continue to put straw in the house? It has a plywood floor. Does it need it? -I've been giving them kitchen scraps and a cupful of feed 2-3 times daily. The flies are many. Should I remove what they haven't eaten at the end of the day or are flies ok? It seems like the, for example, bell pepper tops/stems would break down eventually. We've moved them a few times which they hate. I think they'll stay put for awhile out by the garden. We aren't letting them free range yet. It seems like they get stressed easily and I don't want them to not lay due to stress.
