Our chicks are almost 4 weeks old (hatched around 25th of March). Just now I saw them pecking each others' feathers and eating them. They might be bored - true - our first hatch last year was already out for most of the time at this age, but it is cold now (spring is late and chicks are 1 month earlier this year). Can they have not enough protein too? They are just on chick starter (plus gave them couple apples recently and wheat grass before). The brooder is not very big, but I did not plan to have them there for long - I would like to get them out to the coop in a week or two. I separated two worst peckers just now - they can hear others, but not see. No heat lamp for them, as I only have one - so that separation can't last, I guess. One other chick even has a bloody spot . I hope they'll stop, as I can't separate them one by one. I might get them outside, but it is 54F and wind. Any advice? Buy them a cabbage head? First non-organic thing they would get.
