I would probably do that since that's what those birds have been on. Don't forget to post pictures. The only info I can find in my books is for oral which is 0.4 cc per pound.
Per pound or kilo? Kathy said that 0.18 mg per kilo up to 0.50 mg per kl is the recommended dosage.
Valbazen (albendazole 113.6 mg per ml)
100 mg/kg = 0.88 ml per kg or 0.4 ml per pound
50 mg/kg = 0.44 ml per kg or 0.2 ml per pound
20 mg/kg = 0.18 ml per kg or 0.08 ml per pound
Not sure I would use the 100 mg/kg unless a vet told me to.
