Yesterday my little Silkie girl was limping, eating fine, drinking. This morning she can't move her legs, her wings are down, and she won't eat or drink. I tried to give her molasses water but her crop kind of gurgled so I stopped, she didn't appear to have any breathing problems. Botchulism? They are in a new house, none of the others appear sick. It has been raining, we had a warm front but for the past few days it's been cold/freezing. Mareks? We have had chickens for many years and have had no signs and their not hatchery chicks, but still? Other? She's getting worse by the hour, should I just put her down? Please help, Gerbil.
