I have 10 five week old pullets who are fully feathered and having lots of trouble picking at each other in their brooder. I'm wondering if it might be time to stick them in the big coop. I have 7 hens and none seem to be very aggressive. The run is big, there's a hiding spot under the coop for them to get away to if they're being bothered, and I already have a light on in their coop so I can just swap the normal bulb out for a heat lamp until the chicks get used to the new environment. The temps here range from 38 at night to 55 during the day. I've been decreasing the heat in the brooder and have just today shut off the supplemental heat, as the brooder sits in full sun and gets quite warm on its own. I'm desperate to try to quell this awful picking their doing. Several of them are bloody and I want to see it stopped right away. Thanks for any advice!
