I have six 3-week old Easter Eggs Chicks, two 2-week old barred rocks, and two 2-week old buffs. They are currently all in a 5 foot HW steel trough/brooder. The Araucana's/Easter Egg chicks are INSANE! They fly, squawk, and jump on each other's backs. They all run around the brooder at full speed knocking over their water and their cell mates, feathers are flying... Sometimes the little ones participate in the mosh pit but mostly they move to the outside and watch. Are my birds ok? We spend lots of time with them everyday - holding them, taking them outside, giving them treats - yoghurt and worms. Is this normal behaviour? On top of all of this insanity, the six bigger ones look like they have mange. I think it's just their downy feathers coming out as the new feathers come it. Any thoughts?? Thanks so much!
