We have had 3 pekin drakes for 9 mon got them at 1 day old tsc we never had ducks before, in oct we got 2 buffs & 2 black Swedish hens they are now 3 mon. Everyone shares a 10x20 lot separated in half by chick wire for girls safety guys can be mean at times doubt i will be able to let them live without some barrier ever they can be mean to me and 2 of my kids chasing biting but they can be very sweet and we are extremely attached them, anyway the girls no their place with the boys and respect it for the most part lol we got 4 crested hens in nov. now 7 wks. They go out all day but come in house at dark weather been 20's at night. Every morn they go out and we let the others out to forage for 2-3 hrs then everyone goes to lot crested babies in with 4 3 mon old hens till 3 pm then their all let out till dark here's the problem I suspect the 4 girls are bullying the crest babies during the day maybe not letting eat or enter heated house I am ready to let crested stay out all night and their getting cramped in playpen overnite they seem scared to death of girls and I'm afraid they want let them eat or go into warm house overnite.My plans were to purchase another 10x10 for drakes and all 8 girls could live in 10x20 soon. Lot may be cramped but its best i can do for few weeks.Any suggestions? What I'm doing right or wrong and would the crested babies starve themselves out of fear. Btw girls bully but aren't vicious and when everyone's out they stay in their own little group never intermingling.
