We have a 4 week old chick who cries out in pain when pooping. She does not have pasty butt and is able to make a bowel movement but just lets out a couple of loud painful squawks when pooping. At first I thought she had an infection in her vent and we applied some antibiotic ointment just slightly inside her vent. Still, the screaming is going on, and I feel so bad for her. I am wondering if she might have a constriction inside the vent which would make it impossible to ever lay an egg. Finances are limited and do not permit taking one chicken to the vet for what surely would be hundreds of dollars of x rays, ultra sounds, etc. Please let me hear any thoughts. Our chickens are for pets and eggs only, not eating. This chick is a bantam with feathers on the legs, possibly a salmon favorolle. Our 1st experience raising chicks. Thanks.
