HELP!! We have two baby chicks and they have been housed in a rabbit cage and have had a heat light. 3 weeks old. Feeding chick feed the store suggested, they are still eating, have clean water. i have cleaned the cage every 2 days and water everyday. I turned the light off last night thinking it may be to hot since beginning to get adult feathers in. Seems like one started with it then the other is now doing it? What do you think and how can I help them?
