We have two ducks and a small blue plastic kiddie pool. Can anyone share their advice on changing the pool water out? The pool is in the corner of the run and I have been dumping it out but it's really to heavy to do that plus it pours water into the run which I'm not fond of bc it makes a muddy mess for my chickens. I'm scared to drill a hole in the pool and plug it bc I'm afraid the pool is not strong enough for that and would crack or break. Siphoning seems like a good idea but I don't know what would work best to do that. Thanks in advance for any and all ideas!!
