hi, ive had a chicken whos been really ill shes been in the house for nearly 3 weeks and is still not recovered fully. shes under weight and comb is still pale and dry. she still on antibiotics and im trying to put weight on her but she will only eat the treat food and ignores pellets she also seems really bored so i tried to put her back outside today for fresh air and hopefully to eat some pellets but to my horror the moment i put her down my other two chickens started attacking her! pecking her feathers and chasing her! they have been together from birth and always got on but having her inside so long must have changed something. shes to weak to fight back and i broght her back inside but what the flip do i do now?!!! i have nowhere else to house her. do i keep her in till shes back to healthy and has put weight back on? any advice on what to feed her wouldbe great, shes so thin! or do i lock the others in the mini run and let her have some time outside? this is my run, as you see theres the mini run attatched to the coop. is this normal for them to attack like that? is it because she smell different from being inside? or just because shes been absent??
