Yesterday afternoon I noticed one of my chickens (Tilly) had a large (golf ball), hard crop. I'm new to chickens so wasn't quite sure what it was. Well jumped on trusty BYC and found out about impacted crop. This morning I checked out both hens and found they both had hard, enlarged crops. Also no eggs. So I've given them a couple of massages and managed to soften them up. Now Tilly's has gone but her crop is now larger. It's really swollen and soft and she doesn't like me touching it. She has lay me an egg though. Lucy's is still there but it's not as hard anymore. I've removed their feed but still let them free range. Acting normal. Will my girls be ok?
