I am brand new. Please help. 21 Day old Araucana Chick is holding her mouth open. Looking distressed. She is half the size of her siblings. They came in the mail. all others appear to be healthy. At first I thought she was just hot. But then saw all this dried up crust in her mouth. We have dipped water into her mouth and she does eat and drink. But it dries out because her mouth is held open. I took her to the vet. But it cost me $280 and I can not go again. They said she had a respiratory disease and told us to give her two antiboitics. They are: Itrancolcee and the other does not have a name on the bottle. We have been giving them now for about 6 days but she does not appear to be any better. She is still keeping her mouth open and then it gets dry and crusyt. In addition, today I noticed this red bump thing on her tongue. I looked in my other chicks mouths but don't seem to see anyting similar. Could she have a tumor? I read about gape worm, but the vet looked in her throat and did not see one and also she has never been outside or eaten anything but chick starter. I try to give her water and pick it out but she seems to be in distress. She does peep and makes pretty constant chick noises. She does eat a little and seems to move ok. But she is very tiny and appears to be uncomfortable. My daughter says her crop does get full, but I think that she seems to have trouble eating and drinking. She does peck and stuff and does try but she is so tiny. I have seperated her from other chicks. She has never been outside and has only been fed water and chick starter. Both of which are fresh daily and seem to be just fine by other chicks. She seems warm enough and comfortable except for this open mouth thing. It is weird and I feel so sorry for her. She chirps all the time. I don't know if this is because she is happy that we are always holding her or if she is upset and is chirping. Any advice. Please give me your best ideas as I can not afford another trip to the vet and they just want more money.
