I treated my flock with ivermectin(pour on type) about 2 weeks ago. I noticed my black ameraucana girl in the coop alot. I decided to go check and sure enough she is broody and probably been on the eggs for at least 4 or 5 days(stopped collecting since I was just throwing them away for 3-4 weeks). Are these chicks going to be ok or should I take them? Will the ivermectin have any effect on them?
