Hi me again (I bet you old timers just love us newbies and our billion and one questions ). A quick background to my little new flock. I bought some small but feathered chicks at Christmas time (a sussex, a harco and a Lohmann Brown). They were in separate brooders I believe and just came home together (only 5/7 weeks) with no issues at all. I have been trying to source some Silkies since then to use as mummy hens but the weather and coop building and finding some in colours I wanted conspired against me so instead of happening a couple of months ago I only got them 2 weeks ago. The 2 silkies are between 1 and 2 and both laying. I have them in a separate coop and I have fenced of their own private run in the corner of the day run and the big girls are in the main bit so they can all see each other. On 2 occasions they got to each other, the first was one of the silkies (the more dominant one) got out as I was sorting a bit of fence and one of the others ran over and pecked her. I managed to get her back behind the fence quick smart. Then a few days ago the gate blew open when I was in seeing to the silkies and the big girls wandered in, I just observed and for a few minutes it all seemed well, they were just pecking the ground and being right next to each other etc. Then suddenly they started chasing Hermione (I think Clem' the Lohmann who attacked her the first day started it - she is smallest and I guess lowest on the pecking order although hard to tell as they all just get on so well) I thought I'd let them just see if they could work it out but then they had her pinned to the ground and were pecking her head and pulling her hair - Mabel the Sussex who is also 2 weeks older and quite a lot bigger seemed to take over being the meanest and was the one pinning her down. At that point I ran over and shooed them off and grabbed poor Hermione (who let me hold her and give her a cuddle for the first time!). I know it was too early to try and from then on I've been very careful to fasten the gate every time evne if I'm just going in for a second. The weird thing was they seemed to just totally ignore Doris (the other silkie) one of the hens even kind of sniffed her / put her face right up (maybe trying to work out what she is - she has a total round puffball head!). My plan was to have an intergarted flock and I was hoping having adult silkies (they are not the bantam ones either) to the not even laying (Mabel is 19 weeks the other 2 are 17 weeks) that I may be able to do it but now I'm seriously questioning it. Hopefully the big girls will move into thier coop tomorrow (if we are feeling well enough - dreaded flu lurgy in our house). I just cna't imagine trying to intergrate them after what I saw but don't know if I'm being too soft and it was just normal. The small coop is OK for temporary accommodation for the silkies but wouldn't want to keep them in there permanently and would also like to have them hatch babies and not room for that with both (although I planned it as a future brooder / hospital coop). Part of the plan was that they would bring up the chicks so there wouldn't be intergration issues with new chickens but that clearly won't work if the silkies and my 3 big girls can't get on! The new main coop will hopefully be built in the autumn so I'm wondering if by then they will be used to each other and that would be a good time but if there is then chicks then it will get complicated again! I'm quite happy to run a totally seperate coop (just don't tell my hubby ) and run if I need to but see so many flocks in this area happily running all sizes of chickens together I thought it would be OK! Does anyone think it is even worth trying and if so how / when I should go about it? Is pinning down normal or is that proper bullying? If I need to intervene (either if / when I try to integrate or if there is another jail break) what techniques should I use? Also any tips on when to intervene (other than the blood thing)? I'm guessing with Silkies there has to be a lower tolerance due to the vaulted head issue? Thanks in advance for your thoughts and help.
