I need to find out how to give wormer to my girls. The wormer I bought says to put it in the water. I'm concerned that not all of my girls will get what they need. They seem to enjoy getting water from my goat's water. This also leads me to another question. My girls enjoy going in my goat pen. They like their water and right now the goat shelter seems to be providing relief from the heat for them. Does anyone think this could be a problem for chickens or goats? While I'm on the subject, I'll ask another question. If the poop hole appears to be dirty, is this an indication that something could be wrong. What should I do?
