I only gave them a tiny drop of corid and mostly water. They had VERY little of the medicated feed. I had to remove all the shavings and put them on towels. All day they've been digging like crazy, flicking all of the big pieces of shavings out and eating the small ones. Grr! One Cochin has a huge crop. I took their feed away to see if it'll go down and I massaged all of them a little. I think I've found my problem.
Great!
Keep an eye on them...little buggers are silly sometimes.
