My brother brought home a rabbit that he found on the side of the road. He thought it was wild but to me it looks domestic. It has an agouti coat but its much lighter than wild coloring. Its ears are much longer and its bigger in size than any local wild rabbits. Its a doe and it appears to be young but is an adult. Her friendly and relaxed demeaner also make me think she is a domestic pet. I believe she has a respiratory infection. She is quite thin which I assume is from being loose and not being fed. She sniffles and breathes heavily. I havn't looked in her mouth or nostrils yet because I didn't want to stress her. I put her in a small travel crate with a bowl of food and water and put it in my chicken coop. I will examen her more tomorrow and see what I can do. I really can't afford taking her to a vet right now so I'd like to see what I can do first. If it seems to be getting worse I will take her though. Any suggestions on what to do? I have bred and kept rabbits in the past but have never encountered a RI before please help.
