Hi there, I am looking for some advice re the best worm treatment to buy. We have recently lost two hens - the first we did not know was sick as we were away and the day after we came home she died. As we were away did not notice anything wrong with her. The second hen we noticed this morning was stretching her neck up high as if she was about to make a noise but nothing was coming out. When we realised what was wrong we could not get her medication and gave her a home remedy but it was too late and she died this afternoon. We are now concerned about the rest of the flock and want to treat them asap. Therefore I am looking for what you would recommend and also the best way you have found to administer it. Thank you in advance.
