Hi everyone! I have an sweet little bantam easter egger named Darling that may be showing signs of a respiratory illness. She keeps one of her eyes closed. It doesn't look irritated, red or swollen but she does keep it closed most of the time. I've noticed a few days ago her pecking was off when she tries to pick up food. I notice her itching her nose a lot too. Still eating and drinking but seems more sleepy than the other chicks. Her poops look normal. I would like to nip this in the bud before it gets too bad. I was thinking of starting her on Tylan 50, but I've been searching for an hour and can't find any dosage information for smaller birds/chicks. How much would I give her for injections and for how long? She weighs 443 grams or 15 and 5/8 ounces So she weighs about 1 pound. I'm terrible at math and I don't want to under/over dose her. Any help is greatly appreciated as I want to treat her as soon as possible. Thanks!
