He’s about 2.5 months old. I’ve had him quarantined for lethargy for a few days now & giving corid (he’s doing much better!). Every day I take him out in the yard for a bit and let him forage since he’s in my sun room the rest of the day. Today we were out maybe 10min and he made a sound then suddenly puffed up his feathers and started tipping over! I ran over to get him and he immediately stood back up acting completely normal, then he did it again about 1 min later! After that I put him back in his enclosure and he was completely normal, eating and drinking. It’s warm out but not overly hot (76°f). He has always had mobility issues but nothing serious. I took him to the vet a month ago, they did X-rays and said everything is normal maybe just a mild deformity or growing pains. Is all of this related??
