Greetings friend, It’s empathic reading through your post. Poultry business is a delicate business and requires utmost attention and effort. Sorry about the loss of your chicken. Thank goodness that you were able to find out the problem on time and deal with it before the spread. Hope the technique worked and the other chickens are safe. Do take care and success in the engagement. I can see you are new, welcome to steemit and make the most of your stay here. You would need a lot of patience and consistency and you would do well.
