This is the first crop issue I've come across in my young flock, this is my first flock that I've raised and I didn't know what I was facing at the moment. One of my ameraucana hens, Momo, was visibly having problems with her crop, I first thought sour crop as I've seen the nasty liquid come out of her beak when she would bend her head down. So I attempted to treat her sour crop by emptying it via massaging her crop and holding her almost upside down letting the liquid out. I was careful to make sure she didn't breathe in any of the liquids and frequently gave her breaks. After emptying it a few times spread throughout days with no luck of the crop going down, I tried to isolate her. I didn't think to do this earlier in her treatment becasue I didn't see her eating so to me there was no point (which now I regret). Finally I went to isolate her, setting her up in a spare dog crate. She flipped out and I caved in and let her back with her friends, I felt too bad seeing her pace back and forth the front of the crate bumping her beak on the bars. So thus I let her out which was the worst decision I could've made. I regret it deeply and now do not let sick hens out of isolation because I think they are sad. What I thought was sour crop was also pendulous crop that grew by the day and here we are now, she sleeps standing frequently, walks weird because she cannot see below her, and just overall does not look good. Her crop is humongous filling up both of my hands, I decided to make a "crop bra" which failed miserably, her crop is so large I barley seen a change with the bra on. When I had it on she kept getting her feet stuck in the bottom somehow becasue of how she walks so she would get trapped and fall over which was a miserable sight to see, on top of that when she was stumbling around the first time I put it on, my other chickens went to attack her, I'm assuming because she looked like a threat bumbling around. I was devastated and I'm very disappointed as I seen that crop bra as my last shot. So please help me I'm not sure of what I can do now, I came on here as a last shot for advice as I'm debating putting her down to end her suffering. I don't know how much longer she has, observing her she is really not looking good. I wish to act fast, I don't want to see her suffer anymore and I regret my decisions in the past so much as I've failed my poor Momo.
