Just got one Salmon Favorelle chick, around two/three days old. Named her Ethel. Ethel seems to be very weak, and is wobbly on her legs. She doesn't lie down, but is standing under heat lamp, swaying slightly. She doesn't open her eyes much, ignores the water, food, and other chicks. -We already had two Buff Opringtons, a little over a week old in the brooder. What should we do for her?
