Some of you may remember me, others may not. We have had pet chickens for close to 10 years or so and my family and I know an extensive amount about chicken care, health, etc. Our chickens are free range and are very spoiled. We have a oil heater for them in the winter and a big fan in the summer and it their coop is cleaned every weekend or every other weekend (depends on how much time they spent in the coop vs. outside) We have a hen that's about 2 or 3 yrs old. About 3 weeks ago, we noticed that she had a bulge in her crop that wouldn't go away. We went and got some wormer for chickens and gave it to her for 2 weeks like the bottle said/kept her separated from the others/didnt eat her eggs. Then yesterday I noticed that the bulge was getting bigger and I felt of it and it's very hard, almost like she has a tumor or something but she's not showing any other signs, she's still eating, pooping, drinking, active, etc. We love her and she's one of our favorite ones and I don't want her to die. What could be wrong and also we can't afford to take her to the vet and get a battery of tests done on her. Any advice? BTW, I tried ACV before I tried the wormer, gave it to her for about a week straight, it did nothing at all in the way of helping her. Thanks.
