Her poops look normal, but it wouldnt hurt to worm her as Casportpony mentioned. Dosage for wazine is one ounce per gallon of water for 24 hours only. Since you're treating only one bird, make the one gallon mixture and simply draw enough for your hen for 24 hours. It would be best to provide it in the morning just before she wakes up, that's the time when birds are most hungry and thirsty...she'll readily drink the treated water first thing.
