So in mid January I got 2 bantam pullets at a poultry show, since then they have been quarantined in my basement garage. Today I noticed that one of them has started to make a little "tweet" sound when she breaths. It's almost like she's a little squeaky toy or a harmonica--the sound is on both the inhale and exhale. Every once in a while she gives a little hiccup sound too. There is no discharge or foam from her mouth, eyes, nares. She is not fluffed up nor acting lethargic. She is eating/drinking/pooping normally and her little comb and wattles are normal colored. The "non-squeaky" pullet is breathing fine and just started laying last week. I've only ever gotten one egg at a time so I can't say for sure that the "squeaky" one isn't laying too. Squeaky's comb and wattle aren't as big as the other one's are so I think not, but she's probably pretty close to laying. I changed out their bedding today. They are bedded on chopped hay which is a little dusty. Whenever I change the bedding they do a fair amount of scratching it and throwing it about as well as eating the best bits, so I'm wondering if maybe she just has a little obstruction or irritation. I was going to give it overnight and see if it resolves on its own before I decide to take a peek in her throat tomorrow. If it does not resolve on its own, isn't an obstruction, and instead turns out to be a respiratory illness I will need to decide whether to treat or cull the birds. My decision is complicated by the fact that these birds belong to my 11 year old son. It will be difficult for him if his birds might need to be destroyed. I am lucky to be able to afford vet care if needed but not keen on potentially having carrier birds that I'll have to integrate with the rest of my ladies when the spring thaw comes. I don't sell fertile eggs, chicks, or birds though so a closed flock is possible. I did want to bring in some new chicks someday though. I know all my worry might be premature--the bird might be fine tomorrow. I don't even really have a question, I guess I'm just looking for viewpoints on keeping and treating the birds or culling them and any stories of experiences other might have.
