Hello, I'm new to this so I'm really sorry if I cause an inconvenience to anyone. Please tell me if I'm doing so, so I can correct it. I've never had ducks and I'm trying to get Welsh Harlequin eggs off of online. Either from a farm like Metzer or another website like Ebay. - If anyone has bought eggs from online, how many males and females did you get? I'm worried about getting all males or all females. - Also, how big do Welsh Harlequins get? Anyways, I'm trying to build a duck house before getting the ducks because I've read many posts about how quickly ducks get big. - How many square feet of space do I need for each WH? (I read on other forums that 2ft-6ft, but is 2ft too small for WH? I'm gonna try to keep them outside of their house as much as possible (except maybe during the winter).) - What would be a recommended height for a duck house? (I've read like 2 ft-4ft, but is that the same for all ducks?) - Would the ducks be better if the house was raised? - If I ventilate the top of the box, do I have to cover it with the wire covering, will it be enough ventilation for them, and will they still be warm enough in the winter? Sorry that this is kinda long, I'm just worried I'm gonna mess up something. Thank you.
