About a month ago I lost an Ameracuana hen to what we thought was possibly egg binding. We never found out exactly what it was. Now I have another hen, a Silver Laced Wyandotte, who is acting sick but I can't find any visible signs to show me what it might be. I don't really feel an egg (she's never layed before...she's about 6 months old,) no parasites, her vent is clean. She does appear to have a bit of a raspy wheezing when she breathes. She's listless and really just lays around. We have her isolated in a warm room, have given her epsom salt soaks since yesterday. I started her on Oxytetracycline antibiotic in her water last night. She's still not better. She's not drinking or eating much so I dosed her gently myself just now using an eyedropper so I'm certain she got some of the antibiotic This is what I'm using http://www.tractorsupply.com/en/store/durvetreg;-duramycin-10-6-2-5-oz Is there something else I should be doing? My daughter will be devastated if we lose another one.
