New to raising meat birds. I had a bird flip at four weeks and another one last night (6 weeks). Just wondering if this is normal. I feed 12on and 12 off. They are free range and have been outside for about a week and a half..all day. I do offer flock raiser to them all day..should I restrict it? These are the only two I have lost out of 35 so far...... Secondly...can't them to go in the coop at night. The coop is portable so it sits up about a foot and a half off the ground. I block it off around 8pm so they can't settle in under the coop. I usually end up going out at 9pm and picking up sleeping chickens and putting them to bed! Suggestions? Thanks. Liz in Minnesota!
