Mother hen has been pacing at the enclosure so much that her 4 day old babies were starting to do it too. I know she is eager to get outside and teach the little ones. I let her out and she is out with one other hen. The thing is now they are eating scratch and other things they are finding in the dirt. Is this OK? Also, since I took down the enclosure two hens are eating the medicated food. It is cold out and the chicks are in the run. I know she will warm them but I am used to raising them in a brooder with 90 degree heat lamp at all times. Do I need to trust mother will protect them, keep them warm and get them back up the ramp somehow to drink eat etc...... Thanks.
