I have a 2 month old chick who was raised by his mother until about 2 weeks ago. I had to remove the mother from the coop bc she was starting to be aggressive towards 1 of the chicks (not the chick I'm having issues with) about 2 days later I noticed this little guy was not getting around well so I brought him inside so he would not get trampled. We thought it was spraddle leg and used a hobble for 3 days he appeared to be getting better and actually was able to get on the perch. The following day however he began to go down hill.. he let out his first rooster crow but then was breathing very heavily and began to show signs of weakness again with his front leg extended and toes curled while sitting and falling over while trying to walk. I've tried vet rx, magic water, poultry cell, herbs to promote respiratory health but nothing seems to be helping. I have tylan 50 but I'm hesitant to administer bc he is so light and I'm not sure about the dosage or what is actually wrong so unsure if it will help or hinder. Also he is eating and drinking normally so I don't know what to think. Any information would be appreciated!!
