The crop is not empty in the morning, it has the doughy lump all the time. I'll go ahead and treat her with the copper sulphate when I get it. How long does this treatment usually take to show signs of improvement? Thanks for the response btw.
If this hen with the "doughy" crop is behaving normally, it may be a normal crop. To be certain you are dealing with a legitimate crop issue, monitor the crop in question for a 24 hour period. The crop should be completely empty in the morning before the chicken eats. If the doughy lump is still there in the morning, then you have the option of treating it with copper sulfate or miconazole.
