My 12 week old Silkie is looking like it's not growing very much. I picked it up today and I could feel it's (breast??) bone underneath. It sticks out quite a lot. Is that normal for a Silkie? I'm a bit concerned because it lives with some bossy sussex and it seems to get to the food but it definitely has to wait it's turn. Also a week ago I switched them to cracked grain. The two Silkies don't seem that interested. I had them on chick starter before that but they seemed to lose interest in that once I started feeding them scraps so I asked the local produce store and they said the grain was fine at this age? When I first integrated them I separated the Silkies from the sussex but after a few weeks and some initial running around together they seem to get on for the most part. There are a lot of feathers in the run too but do the silkies lose baby feathers? Anyone got any info? Any thoughts would be appreciated.
