Wow. I'd try to empty those like in the link I posted.

This might be easier with so many affected birds.

I would suggest you check their crops in the morning...all crops should be empty when you examine them first thing..it is usual for a crop to be full in the evenings...some of mine have crops that look fit to burst at the end of their day...the crops are always empty by morning...

They're not usually like this. The one black and white one is the worst. She's getting worse everyday. The others are acting normal. Pop takes cars of them most of the time because I work a lot. I'll pass all this information to him so he can treat them ASAP..

Is there any foul smell to their breath...? If so they may have sour crop...see the sticky's at the top of the Emergencies etc page..scroll down to Helpful references and links..click on that and scroll down to Medical treatment and dosage..there is great information on crop issues..read it and it should give you all the information you will need to treat them if that is the problem...
